An in vitro method was used to assess the bioaccessibility of phenolics, flavonoids, carotenoids, and capsaicinoid compounds in different cooked potatoes mixed with roasted peppers (Capsicum annuum), Joe Parker (JP, hot), and Sweet Delilah (SD, sweet). The present study identified differences in the bioaccessibility of bioactive compounds among the potato cultivars (Solanum tuberosum) Purple Majesty (PM; purple flesh), Yukon Gold (YG; yellow flesh), Rio Grande Russet (RG; white flesh) and a numbered selection (CO 97226-2R/R (R/R; red flesh)). The bioactive compounds and capsaicinoid compounds in potatoes and peppers were estimated before and after in vitro digestion. Before digestion, the total phenolic content of potato cultivars mixed with JP was in the following order: R/R > PM > YG > RG. The highest levels of carotenoids were 194.34 µg/g in YG and 42.92 µg/g in the RG cultivar when mixed with roasted JP. The results indicate that the amount of bioaccessible phenolics ranged from 485 to 252 µg/g in potato cultivars mixed with roasted JP. The bioaccessibility of flavonoids ranged from 185.1 to 59.25 µg/g. The results indicate that the YG cultivar mixed with JP and SD showed the highest phenolic and carotenoid bioaccessibility. In contrast, the PM mixed with JP and SD contained the lowest phenolic and carotenoid bioaccessibility. Our results indicate that the highest flavonoid bioaccessibility occurred in R/R mixed with roasted JP and SD. The lowest flavonoids bioaccessibility occurred in PM and the RG. The maximum bioaccessible amount of capsaicin was observed in YG mixed with JP, while the minimum bioaccessibility was observed with PM.

Meloidogyne chitwoodi is a major threat to potato production in the Pacific Northwest region of United States. Infected tubers are rendered unmarketable, hence growers’ profitability is adversely affected. Breeding for nematode resistance is a long-term process and phenotyping the segregating populations for nematode resistance is the most time-consuming and laborious part of the process. Using DNA-based markers closely linked to the nematode resistance trait for marker-assisted selection (MAS) could enhance breeding efficiency and accuracy. In the present study, a pool of phenotyped progenies segregating for nematode resistance and susceptibility were fingerprinted using a 21K single nucleotide polymorphism (SNP) array. Eight candidate SNPs located on potato Chromosome 11, segregating with the nematode resistance trait were identified and used as landmarks for discovery of other marker types such as, simple sequence repeat (SSR) and insertion-deletion (INDEL) markers. Subsequently, a total of eight SNPs, 30 SSRs and four INDELS located on scaffold 11 of Solanum. bulbocastanum were used to design primers; markers were validated on a panel of resistant and susceptible clones. Two SNPs (SB_MC1Chr11-PotVar0066518 and SB_MC1Chr11-PotVar0064140), five SSRs (SB_MC1Chr11-SSR04, SB_MC1Chr11-SSR08, SB_MC1Chr11-SSR10, SB_MC1Chr11-SSR13 and SB_MC1Chr11-SSR20) and one INDEL (SB_MC1Chr11-INDEL4) markers differentated between the resistant and susceptible clones in the test panel as well as other segregating progenies using simple PCR technique and high resolution melting curve analysis. These markers are robust, highly reproducible and easy to use for MAS of nematode resistant potato clones to enhance the breeding program.

Meloidogyne chitwoodi is one of the most devastating pests of potato in the U.S. Pacific Northwest (PNW). Nematode-infected tubers develop external as well as internal defects, making the potatoes unmarketable, and resulting in economic losses. Draft genome assemblies of three M. chitwoodi genotypes, Mc1, Mc2 and Mc1Roza, were generated using Illumina and PacBio Sequel RS II sequencing. The final assemblies consist of 30, 39 and 38 polished contigs for Mc1, Mc2 and Mc1Roza, respectively, with average N50 of 2.37 Mb and average assembled genome size of ~47.41 Mb. An average of 10,508 genes were annotated for each genome. BUSCO analysis indicated that 69.80% of the BUSCOs were complete whereas 68.80%, 0.93% and 12.67% were single copy, duplicated and fragmented, respectively. These highly contiguous genomes will enrich resources to study potato-nematode interactions and enhance breeding efforts to develop nematode resistant potato varieties for PNW.

Potassium (K) is a primary macronutrient for overall plant growth, yield potential, product quality and stress resistance of crops. Potato (Solanum tuberosum L.) crops require a high amount of potassium to achieve the ideal yield and quality. Therefore, the determination of optimum K rate and efficient source for potato is necessary because K affects crop physiological processes, dry matter production, cooking, and processing requirements. Through modeling on the pooled data extracted from 62 studies, the highest tuber yields might be obtained at an exchangeable soil K level of 200 mg kg−1 approximately, dependent on soil pH, texture, and organic matter. Through modeling on the data of 48 studies, it also revealed that application of potassium sulfate (K2SO4) and potassium chloride (KCl) at rates of 200 kg ha−1 and potassium nitrate (KNO3) at a rate of 100 kg ha−1 might achieve the ideal yield, implying the importance of K sources in potato production. However, these values (either soil exchangeable K content, or fertilizer rates) might not be applicable in a specific growing environment for a specific potato variety. It seems that there is no discrimination among split, pre-plant or in-season application of K, although pre-plant fertilization might be a trustworthy strategy for economic tuber yield. Owing to the luxury consumption of K by potato crop, a combination of factors, including soil exchangeable K level, petiole K concentration, crop removal amount, soil conditions, management practices, climatic conditions, and potato variety, should be considered in order to make rational K fertilizer recommendations.

The effect of speed and duration of ventilation fans on the quality of russet potatoes (Rio Grande Russet) stored at 5 °C ± 2 and 95 % RH ± 5 in 2016 and 2017 seasons was investigated. Three fans moved air at three rates: 52 cubic feet per minute (CFM), 13 CFM, or 0.6 CFM and operated under continuous or intermittent control. This investigation included a zero-ventilation control. The tubers were analyzed periodically for weight loss, texture, ethylene production, respiration rate, sprouting incidence, power consumption, and nutritional value (total phenolics, total flavonoids, reducing sugars, and ascorbic acid) during the storage period. The results indicated that the rate of weight loss was higher under continuous high CFM ventilation. Intermittent ventilation at 0.6 CFM significantly reduced weight loss and have turgid tubers when compared with the control. There was a significant difference in sprouting rate and power consumption between continuous and intermittent ventilation. Continuous ventilation at 52 CFM significantly increased total flavonoid content and decreased reducing sugars compared to intermittent ventilation at 0.6 CFM. This study indicates the importance of using slow and medium CFM fans in long-term potato storages to reduce tuber weight loss and power consumption.

Background Meloidogyne chitwoodi commonly known as Columbia root-knot nematode or CRKN is one of the most devastating pests of potato in the Pacific Northwest of the United States of America. In addition to the roots, it infects potato tubers causing internal as well as external defects, thereby reducing the market value of the crop. Commercial potato varieties with CRKN resistance are currently unavailable. Race specific resistance to CRKN has been introgressed from the wild, diploid potato species Solanum bulbocastanum into the tetraploid advanced selection PA99N82–4 but there is limited knowledge about the nature of its resistance mechanism. In the present study, we performed histological and differential gene expression profiling to understand the mode of action of introgressed CRKN resistance in PA99N82–4 in comparison to the CRKN susceptible variety Russet Burbank. Results Histological studies revealed that the nematode juveniles successfully infect both resistant and susceptible root tissue by 48 h post inoculation, but the host resistance response restricts nematode feeding site formation in PA99N82–4. Differential gene expression analysis shows that 1268, 1261, 1102 and 2753 genes were up-regulated in PA99N82–4 at 48 h, 7 days, 14 days and 21 days post inoculation respectively, of which 61 genes were common across all the time points. These genes mapped to plant-pathogen interaction, plant hormonal signaling, antioxidant activity and cell wall re-enforcement pathways annotated for potato. Conclusion The introgressed nematode resistance in PA99N82–4 is in the form of both pattern-triggered immune response and effector-triggered immune response, which is mediated by accumulation of reactive oxygen species and hypersensitive response (HR). Salicylic acid is playing a major role in the HR. Polyamines and suberin (a component of the Casperian strip in roots) also play an important role in mediating the resistance response. The present study provides the first ever comprehensive insights into transcriptional changes among M. chitwoodi resistant and susceptible potato genotypes after nematode inoculation. The knowledge generated in the present study has implications in breeding for CRKN resistance in potato.

Conventional wisdom regarding potato breeding indicates that a strong triploid block prevents the development of viable triploid seeds from crosses between tetraploid and diploid clones. However, in a recent set of crosses between elite tetraploid potatoes and an improved diploid hybrid population derived from group Stenotomum and group Phureja, 61.5% of the resulting clones were found to be triploid. If clones derived from one diploid parent suspected of producing a high frequency of unreduced gametes were excluded, then the frequency of triploid clones increased to 74.4%. Tubers of these triploids are generally intermediates of the two parental groups. Our findings indicate the possibility of using triploid potatoes in potato variety development programs and in genetic and genomic studies.

The National Chip Processing Trial is a collaborative effort between public breeding programs and the potato (Solanum tuberosum L.) industry to identify new clones with broad adaptation. The objective of this study was to investigate the genetic covariance of trial locations, based on 337 clones evaluated in 10 states from 2011 to 2016. Three models were considered: (I) assuming a uniform genetic correlation between locations within a year, (II) using a factor-analytic (FA) model of the total genetic covariance of environments (location–year combinations), and (III) using a FA model of the additive genetic covariance based on 5278 single-nucleotide polymorphism (SNP) markers. With Model I, the genetic correlation between locations was 0.50 for vine maturity, 0.54 for tuber yield, and 0.72 for specific gravity. The Akaike information criterion decreased as model complexity increased, from Models I to II to III, for maturity and yield but not specific gravity. Of the 10 states in the dataset, Florida stood out for having environments with substantial (up to 88%) genetic variance unexplained by the latent factors. Linear discriminants (LD) of the factor loadings were used to visualize the genetic correlation between locations. For vine maturity, LD1 separated Florida from the other locations, and LD2 separated the remaining southern locations from the northern ones. For yield, LD1 separated Texas from the other locations. This study has created a foundation for the design of more efficient trialing and selection programs for the US potato community. Copyright © 2018. .

DNA fingerprinting is a powerful tool for plant diversity studies, cultivar identification, and germplasm conservation and management. In breeding programs, fingerprinting and diversity analysis provide an insight into the extent of genetic variability available in the breeding material, which in turn helps breeders to maintain a pool of highly diverse genotypes by avoiding the selection of closely related parents. Oblong-long tubers with russeting skin characterize Russet potato, a primary potato market class in the United States, and especially in the western production regions. The aim of this study was to estimate the level of genetic diversity within this market class potato, utilizing clones and varieties from various breeding programs across the United States. A collection of 264 Russet and non-Russet breeding clones and varieties was fingerprinted using 23 highly polymorphic genome-wide simple sequence repeat (SSR) markers, resulting in 142 polymorphic alleles. The number of alleles produced per SSR varied from 2 to 10, with an average of 6.2 alleles per marker. The polymorphic information content and expected heterozygosity of SSRs ranged from 0.37 to 0.89 and 0.50 to 0.89 with an average of 0.77 and 0.81, respectively. Out of these 23 markers, we propose nine SSR markers best suited for fingerprinting Russet potatoes based on polymorphic information content, heterozygosity and ease of scoring. Diversity analysis of these clones suggest that there is significant diversity across the breeding material and the diversity has been evenly distributed among all the regional breeding programs.

Meloidogyne chitwoodi (Columbia root-knot nematode, CRKN) can cause serious damage in potato production systems, decreasing tuber value in the fresh market and processing industries. Genetic resistance to CRKN was first identified from the wild diploid potato species Solanum bulbocastanum accession SB22 and was successfully introgressed into tetraploid potato breeding material. To expand the base of genetic resistance, 40 plant accessions representing nine wild potato species were screened for their resistance to M. chitwoodi. Greenhouse screening identified fifteen clones from S. hougasii, one clone from S. bulbocastanum, and one clone from S. stenophyllidium with moderate to high levels of resistance against three isolates of M. chitwoodi. Geographical mapping showed that the resistance sources identified in this and previous studies primarily originated in the states of Jalisco and Michoacán in west-central Mexico. These new sources of resistance will be introgressed into elite potato populations to facilitate the development of potato cultivars with durable resistance to M. chitwoodi. Meloidogyne chitwoodi (nematodo agallador de Columbia, CRKN por sus siglas en inglés), puede causar daño serio en los sistemas de producción de papa, disminuyendo el valor del tubérculo en el mercado fresco y en las industrias del procesamiento. La resistencia genética al CRKN se identificó primero en la especie silvestre diploide de papa Solanum bulbocastanum, accesión SB22, y fue introducida con éxito en material tetraploide de mejoramiento de papa. Con el fin de expandir la base de resistencia genética, se probaron 40 plantas de las accesiones, representando nueve especies silvestres de papa, para su resistencia a M. chitwoodi. En las pruebas de invernadero se identificaron 15 clones de S. hougasii, uno de S. bulbocastanum, y uno de S. stenophyllidium, con niveles de moderados a altos de resistencia contra tres aislamientos de M. chitwoodi. El mapa geográfico mostró que las fuentes de resistencia identificadas en este y en estudios previos, se originaron primeramente en los Estados de Jalisco y Michoacán, en el centro-occidente de México. Estas nuevas fuentes serán introducidas a poblaciones élite de papa para permitir el desarrollo de variedades de papa con resistencia durable a M. chitwoodi.

Micronutrient deficiency, also known as the hidden hunger, affects over two billion people worldwide. Potato is the third most consumed food crops in the world, and is therefore a fundamental element of food security for millions of people. Increasing the amount of micronutrients in food crop could help alleviate worldwide micronutrient malnutrition. In the present study, we report on the identification of single nucleotide polymorphism (SNP) markers associated with folate, an essential micronutrient in the human diet. A high folate diploid clone Fol 1.6 from the wild potato relative Solanum boliviense (PI 597736) was crossed with a low/medium folate diploid S. tuberosum clone USW4self#3. The resulting F1 progeny was intermated to generate an F2 population, and tubers from 94 F2 individuals were harvested for folate analysis and SNP genotyping using a SolCap 12K Potato SNP array. Folate content in the progeny ranged from 304 to 2,952 ng g-1 dry weight. 6,759 high quality SNPs containing 4,174 (62%) polymorphic and 2,585 (38%) monomorphic SNPs were used to investigate marker-trait association. Association analysis was performed using two different approaches: survey SNP-trait association (SSTA) and SNP-trait association (STA). A total of 497 significant SNPs were identified, 489 by SSTA analysis and 43 by STA analysis. Markers identified by SSTA were located on all twelve chromosomes while those identified by STA were confined to chromosomes 2, 4, and 6. Eighteen of the significant SNPs were located within or in close proximity to folate metabolism-related genes. Forty two SNPs were identical between SSTA and STA analyses. These SNPs have potential to be used in marker-assisted selection for breeding high folate potato varieties.

Specific gravity (SpGr) is often used to measure the processing quality of potato (Solanum tuberosum L.) tubers for French fries or potato chips because of its strong correlation with dry matter content and ease of measurement. For French fry processing genotypes, the desirable range for mean SpGr is typically 1.080 to 1.095, and a small variance around the mean is essential for product uniformity. Two multi-year, multi-location trials were conducted to investigate the genetics of SpGr in elite russet germplasm. Consistent with earlier studies, the mean SpGr was measured with high repeatability within each environment: the median plot-basis value was 0.83 for a national trial with six locations and 3 yr. In contrast, the median repeatability of the SD between tubers was only 0.21. Thus, multi-environment trials are needed to identify genotypes with a narrow SpGr distribution. Finlay–Wilkinson stability analysis of the mean SpGr established one genotype as an outlier: when best linear unbiased predictions were regressed on the environment means, this genotype had a regression coefficient of 2.1, compared with 0.4 to 1.4 for the others. The genetic correlation between environments showed a consistent regional pattern in mean SpGr over the years. There was a higher mean correlation between environments within the Pacific Northwest (0.97), Upper Midwest (0.91), and Northeast (0.85) than between environments from the different regions (0.35–0.78). Although breeding for national adaptation is an attractive idea, our results suggest that genetic gain may be easier to achieve at the regional level. Copyright © 2017. .

Sage Russet was released in 2009 by Oregon State University, in cooperation with the USDA-ARS and the Agricultural Experiment Stations of Idaho and Washington. It is a product of the Northwest Potato Variety (Tri-State) Development Program. Sage Russet has a medium-early maturity and produces long, somewhat flattened tubers with medium russeting of the skin. Total yields of Sage Russet are similar to those of Russet Burbank and Ranger Russet, but are significantly higher than those of Russet Norkotah. Sage Russet has significantly higher U.S. No.1 yields than Russet Burbank, Russet Norkotah, and Ranger Russet. It can be grown as an early or late crop with high U.S. No.1 yields and minimal internal defects. It achieved very high merit scores in processing and fresh market in Western Regional trials and can be considered for both markets. Sage Russet has a medium to high fertility requirements with high nitrogen use efficiency and medium storage capability. Sage Russet has moderate specific gravity and produces lighter fry color than the industry standard varieties. The color of fried strips following tuber storage at 4.4 °C and 7.2 °C is significantly lighter for Sage Russet than the control varieties, indicating good cold sweetening resistance. Chemical analyses have shown that Sage Russet has higher protein and vitamin C content than control varieties. Sage Russet is moderately resistant to early dying, early blight, and common scab, is resistant to tuber late blight, but susceptible to Fusarium wilt and is prone to shatter bruise. Sage Ruset se liberó en 2009 por la Universidad del Estado de Oregon, en cooperación con el USDA-ARS y las Estaciones Agrícolas Experimentales de Idaho y Washington.

Reliable pedigree information facilitates a scientific approach to breeding, but errors can be introduced in many stages of a breeding program. Our objective was to use single nucleotide polymorphisms (SNPs) to check the pedigree records of elite North American potato germplasm. A population of 719 tetraploids was genotyped with an Infinium SNP array, yielding 5063 high-quality markers. Based on pedigree records, the dataset contained 198 parent-offspring trios, of which 182 were consistent with the marker data. For 13 of the 16 trios with a pedigree error, the true parent was identified in the population. By comparing the additive relationship matrix calculated from pedigree with the genetic distance calculated from markers, an additional 24 pedigree modifications were proposed, including the paternity of several varieties developed with bulk pollen. To ensure accurate pedigree records are published in the future, we recommend that new varieties be SNP genotyped and checked against this dataset. La información confiable sobre el pedigree facilita un enfoque científico para el mejoramiento genético, pero se pueden introducir errores en muchas etapas de un programa de mejoramiento. Nuestro objetivo fue usar polimorfismos de un solo nucleótido (SNPs) para cotejar los archivos de pedigree de germoplasma élite de papa de Norteamérica. Una población de 719 tetraploides fue genotipada con una colección de SNPs en una plataforma Infinium, obteniendo 5063 marcadores de alta calidad. Con base a los records del pedigree, la hoja de datos contenía 198 tríos de descendientes con sus padres, de los cuales 182 fueron consistentes con los datos de marcadores. Para 13 de 16 tríos con error de pedigree, se identificó al progenitor verdadero en la población. Al comparar la matriz de relación aditiva calculada del pedigree con la distancia genética calculada de los marcadores, se propusieron 24 modificaciones adicionales al pedigree, incluyendo la paternidad de varias variedades desarrolladas con polen masivo. Para asegurar que a futuro sean publicados registros precisos de pedigree, recomendamos que las nuevas variedades sean genotipadas utilizando SNPs y se cotejen con esta hoja de datos.

The Northwest Potato Variety Development (NWPVD) Program has released 45 improved potato varieties since 1985. Thirty-four potato varieties, four breeding clones and two advanced selections from NWPVD Program, and six commonly-grown potato varieties were fingerprinted using 32 simple sequence repeat (SSR) markers and 12,808 single nucleotide polymorphism (SNP) markers. Of 32 SSR markers, 29 exhibited significant polymorphism across all the 46 potato clones studied. A total of 143 alleles were observed with an average of 4.6 alleles per SSR marker. These markers span all 12 chromosomes of potato, with a maximum of five markers from chromosome VIII and minimum of one marker from chromosome VI. The polymorphic information content (PIC) and expected heterozygosity (He) of the SSR markers ranges between 0.18 to 0.75 and 0.20 to 0.78, respectively. Based on PIC, He, and ease of scoring, we recommend a set of eight SSR markers: STG0016, STI0004, STI0012, STI0023, STI0030, STI0033, STM1016 and STM1104 for fingerprinting NWPVD varieties. Out of 12,808 SNPs, 88.8% resulted in reliable three cluster diploid calling of which 87.8% were polymorphic. Tetraploid calling resulted in 44.2% of SNPs of which 94.5% were polymorphic. Our study provided fingerprinting resources for the NWPVD varieties and can be used in issues related to intellectual property rights, ownership, trademark and diversity analysis.

Yukon Nugget is a mid-season specialty potato with yellow flesh, yellow skin and distinct red eyes. Yukon Nugget was developed to provide the potato industry with an alternative to Yukon Gold. The overall tuber size profile of Yukon Nugget is smaller and more uniform than Yukon Gold and it typically produces an average of four more tubers per plant than Yukon Gold. Yukon Nugget tubers are ideal for boiling, baking, and microwaving, and have culinary and nutritional qualities generally similar to Yukon Gold. Yukon Nugget has extreme resistance to Potato Virus X due to presence of PVX resistance allele Rx1. It also has moderate resistance to powdery scab and tuber late blight. Yukon Nugget has less vascular and stem end discoloration and less hollow heart than Yukon Gold. Yukon Nugget is similar to Yukon Gold in terms of susceptibility to several major potato diseases, such as PVY, PLRV, and foliage late blight. It was released in 2013 by the Agricultural Experiment Stations of Oregon, Idaho and Washington and the USDA-ARS, and is a product of the Pacific Northwest (Tri-State) Potato Variety Development Program.

The third most important food crop worldwide, potato (Solanum tuberosum L.) is a tetraploid outcrossing species propagated from tubers. Breeders have long been challenged by polyploidy, heterozygosity, and asexual reproduction. It has been assumed that tetraploidy is essential for high yield, that the creation of inbred potato is not feasible, and that propagation by seed tubers is ideal. In this paper, we question those assumptions and propose to convert potato into a diploid inbred line–based crop propagated by true seed. Although a conversion of this magnitude is unprecedented, the possible genetic gains from a breeding system based on inbred lines and the seed production benefits from a sexual propagation system are too large to ignore. We call on leaders of public and private organizations to come together to explore the feasibility of this radical and exciting new strategy in potato breeding. Copyright © 2016. .

Malnutrition is one of the world’s largest health concerns. Folate (also known as vitamin B9) is essential in the human diet, and without adequate folate intake, several serious health concerns, such as congenital birth defects and an increased risk of stroke and heart disease, can occur. Most people’s folate intake remains sub-optimal, even in countries that have a folic acid food fortification program in place. Staple crops, such as potatoes, represent an appropriate organism for biofortification through traditional breeding based on their worldwide consumption and the fact that modern cultivars only contain about 6% of the daily recommended intake of folate. To start breeding potatoes with enhanced folate content, high folate potato material must be identified. In this study, 250 individual plants from 77 accessions and 10 Solanum species were screened for their folate content using a tri-enzyme extraction and microbial assay. There was a 10-fold range of folate concentrations among individuals. Certain individuals within the species Solanum tuberosum subsp. andigenum, Solanum vernei and Solanum boliviense have the potential to produce more than double the folate concentrations of commercial cultivars, such as Russet Burbank. Our results show that tapping into the genetic diversity of potato is a promising approach to increase the folate content of this important crop.

To the best of our knowledge, one or more authors of this paper were federal employees when contributing to this work. This is the publisher’s final pdf. The published article is copyrighted by Elsevier and can be found at: http://www.journals.elsevier.com/european-journal-of-agronomy/.Global plant genetics research efforts have focused on developing high yielding, stress tolerant, and\ud disease resistant row and field crop varieties that are more efficient in their use of agronomic inputs\ud (water, nutrients, pesticides, etc.). Until recently, a key bottleneck in such research was the lack of\ud high-throughput sensing technologies for effective and rapid evaluation of expressed phenotypes under\ud field conditions for holistic data-driven decision making and variety selection. This review focuses on\ud technological aspects of integrating unmanned aerial vehicles with imaging systems to enhance field\ud phenotyping capabilities. The state-of-the-art of unmanned aerial vehicle technology for various applications\ud including crop emergence, vigor, and characterization of yield potential of row and field crops has\ud been reviewed. The potential of using aerial imaging to evaluate resistance/susceptibility to biotic and\ud abiotic stress for crop breeding and precision production management has been discussed along with\ud future perspectives and developments
