Strawberries are grown worldwide, and the fruit is known for its flavor, pleasant aroma, and the presence of important nutraceutical compounds. Under temperate conditions, the species is octaploid and presents a complex inheritance. Exploring polyploidy in varietal crosses is the main alternative to developing genotypes of high-temperature regions; thus, breeding programs must evaluate the interaction based on parameters, such as the heritability, stability, easy propagation, and adaptability to different soil and climate variations. To estimate the stability and temporal adaptability of pre-selected triple hybrids of day-neutral strawberries, thirty-six experimental genotypes, three commercial genotypes (‘Albion,’ ‘Monterey,’ and ‘Dover’), and four single hybrids (‘RVFS07,’ ‘RVFS06,’ ‘RVDA11,’ and ‘RVCA16’) were evaluated in a protected cultivation from August to February under tropical climate conditions (southern hemisphere) using the mixed linear model (MLM). The genotypes RVFS07M-34, RVFS07M-24, RCDA11M-04, RVFS07M-154, RVFS07M-36, RVFS07M-33, RVFS07M-80, RVFS07M-10, RVDA11M-21, RVDA11M-13, and RVFS06AL-132 had the highest values of total fruit mass, adaptability, and stability. The mean predicted genotypic values of the selected genotypes was 138% higher than the mean of the controls. Therefore, these genotypes have the potential to be released as cultivars.

Arthropod pests are among the biggest problems faced in tomato production worldwide. To overcome the losses caused by these pests, one of the most sustainable and economical strategies is the use of resistance introgressed from wild species. We aimed to develop BC₃F₂ tomato genotypes with high levels of zingiberene (ZGB) and resistance to whitefly (Bemisia tabaci biotype B), South American tomato pinworm (Tuta absoluta), and the two-spotted spider mite (Tatranychus urticae), from the wild accession of Solanum habrochaites var. hirsutum (accession PI127826). The quantification of ZGB in 520 BC₃F₂ genotypes and in the parentals yielded the selection of five genotypes with high ZGB content and three with low ZGB content, which were then infested with B. tabaci, T. absolute, and T. urticae. In these eight genotypes and in the parents, the types and amounts of trichomes on the leaves were determined. Additionally, molecular markers were used to identify the genotypes with a higher recurrent genome recovery. The results confirmed the transfer of resistance from S. habrochaites to the BC₃F₂ genotypes and showed that this resistance seems to be directly related to high concentrations of ZGB and the presence of type IV trichomes.
