A study was conducted by using twenty one (21) F₉ populations derived from inter-varietal crosses of Brassica rapa L. Path co-efficient analysis revealed that plant height, number of primary branches per plant, number of siliqua per plant, seeds per siliqua, and siliqua length had the positive direct effect on yield per plant and days to 50% flowering, number of secondary branches per plant, and thousand seed weight had the negative direct effect on yield per plant. Correlation studyrevealed that yield per plant had significant positive association with plant height, number of primary branches per plant, number of siliqua per plant, seeds per siliqua, and siliqua length (genotypic or phenotypic level). Based on the variability study, some F₉ plants showed high heritability for short duration and yield contributing characters were selected from some of the crosses combinations of the intervarital crosses of Brassica rapafor further selection.

An experiment was conducted at Research and Development (Vegetable) Farm, Supreme Seed Company Limited, Mymensingh in 20th March to 14th June, 2013 to evaluate performance of eight snake gourd genotypes. Among snake gourd genotypes four were test hybrid viz. SG1001, SG1002, SG1003 and SG1004 (from the seven inbreed lines) and four were checks (three from local market and one from BADC) viz. SUPREMA, RUNNER, SURMA, ZUM LONG. Wide ranges of variability were found in the studied characters among the genotypes. Maximum total number of fruits was found from SUPREMA (235.3/plot) which was statistically similar to RUNNER (201.3/plot) while minimum from ZUM LONG (24.7/plot) that was used as check. SG1002 genotype provided maximum marketable yield (49.6 kg/plot) and minimum from ZUM LONG (30.7 kg/plot). SUPREMA, SG1002, SG1001 and RUNNER genotypes showed better performance in respect of number of fruits/plant, fruit length, individual fruit weight, yield/plot and some other characters. Flowering period was significantly correlated with yield contributing characters. Number of fruits/plant, total number of fruits/plot and individual fruit weight was significantly positively correlated with yield of snake gourd.

Single nucleotide polymorphisms and restriction digestion-based haplotype variations among 160 flood prone rice varieties were analyzed with enzymes Alu I and Cac8 I to generate polymorphisms at Sub1A and Sub1C loci (conferring submergence tolerance), respectively. Haplotype associated with phenotype was used to study the haplotype variations at Sub1A and Sub1C loci and to determine their functional influence on submergence tolerance and stem elongation. Three patterns at Sub1A locus, Sub1A0 (null allele), Sub1A1 (does not cut) and Sub1A2 (one SNP), and four patterns at Sub1C locus, Sub1C1, Sub1C2, Sub1C3 and Sub1C4, were generated. Both tolerant Sub1A1 and intolerant Sub1A2 had the same length, but the difference was presence of a restriction site in the Sub1A2, but absent at the Sub1A1. Further, two types of polymorphism were detected at the Sub1C, one included major length polymorphisms (165, 170 and 175 bp) and the other was a single restriction site at different position. Eight haplotypes (different combinations of the two loci), A1C1, A1C2, A1C4, A2C2, A2C4, A0C2, A0C3 and A0C4, were detected among 160 varieties. Haplotype A1C1 was comparatively more related to haplotypes A1C2 and A1C4, having the same Sub1A allele, and these haplotypes were found only in Bangladeshi, Sri Lankan and Indian varieties. Most tolerant varieties in A1C1 haplotype showed slow elongation, having tolerant specific Sub1A1 and Sub1C1 alleles. Further, the varieties Madabaru and Kottamali (A2C2) also showed moderate level of tolerance without Sub1A1 allele. These varieties were different with FR13A and also suspected to carry different novel tolerant genes at other loci. These materials could be used for hybridization with Sub1 varieties for pyramiding additional tolerant specific alleles into a single genotype for improving submergence tolerance in rice

This article presents dataset on agromorphogenic traits of Aloe vera treated by foliar application of Zn (zinc) and vermicompost. Data from yield and yield related characters with morphological traits were collected to assess the effect of vermicompost and Zn. The data showed in this dataset article contained 17 agronomic and morphological traits. The collected data were analyzed using excel, statistix 10.0 and STAR software. The analyzed data presented with the help of ANOVA (analysis of variance), mean comparison, correlation co-efficient and principal component analysis (PCA). Data of microclimate, correlation co-efficient and biplot distribution of principal components were presented graphically. The aim of the article is to ensure the data easily accessible and as a brief source of agricultural management information for crop development and production for researcher.

Low temperatures are a major environmental stress that limits plant growth and development. Understanding the molecular mechanism of cold tolerance is therefore essential for improving crop performance through molecular breeding. In this study, we focused on CISP, a small, previously uncharacterized protein, specifically induced in barley roots under low temperature conditions, and investigated its potential role in cold tolerance. Heterologous expression of CISP in Escherichia coli enhanced late‐phase bacterial growth at low temperatures compared with the wild‐type strain. Similarly, overexpression of CISP in Arabidopsis thaliana , which lacks an apparent ortholog, improved seedling growth under low temperature conditions. These results suggest that CISP can promote growth of heterologous organisms used in this study at low temperature environments. To investigate its molecular function, we performed RNA chaperone assays using RNA beacons that tend to form stable secondary structures. CISP reduced the formation of RNA secondary structures and facilitated their destabilization, indicating RNA chaperone–like activity. CISP is a basic, low‐molecular‐weight protein containing an intrinsically disordered region (IDR) at its N‐terminus but lacking canonical RNA‐binding domains such as the cold shock domain (CSD) or RNA recognition motif (RRM). Our findings therefore suggest that CISP may represent a previously uncharacterized type of RNA chaperone. This study provides new insights into the structure and function of CISP and its potential contribution to cold tolerance in barley.
