Summary: The study analyzed the genotype data of Cucurbita pepo, C. moschata, and C. maxima collected from USDA germplasm collections through genotyping-by-sequencing. The analysis revealed extensive genetic structure corresponding to geographical origin and morphotype/market class. Genome-wide associate studies identified signals for various traits, with the strongest signal found for the bush gene in C. pepo. This research provides valuable information for maintaining genetic diversity, developing breeding resources, and prioritizing whole-genome re-sequencing.

Summary: Eggplant is the fifth economically important vegetable in the Solanaceae family, including cultivated eggplant and two underutilized species. The breeding program aims to improve fruit quality, increase yield through heterosis breeding, and introduce resistance from wild relatives. The study focuses on genetic resources, stress resistance, pre-breeding, and sustainable eggplant breeding.

Summary: The study evaluated 54 rice genotypes for RYMV resistance and agronomic traits in Tanzania, identifying seven genotypes with moderate to high resistance. Positive correlations were found between grain yield and traits such as number of panicles per plant, panicle length, and thousand-grain weight, providing useful information for rice yield improvement. The principal component analysis identified key traits contributing to variability in the germplasm collection, with genotypes such as Rangimbili, Gigante, and SARO showing promise for further breeding efforts.

Summary: This study investigated the genetic diversity of Spanish peach germplasm using genotyping and genetic association analysis. The results showed that the new SNP array allowed for better identification of genetic similarity and possible gene variation events. Additionally, the analysis of trait-SNP associations for leaf glands, fruit hairiness, and flesh texture provides valuable information for marker-assisted breeding and crossing approaches in peach breeding programs.

Summary: This study conducted identification and analysis of the genetic structure and cultivars of walnuts in China. The research found low genetic diversity and high clonality in cultivated varieties, but the two species of walnuts can still be distinguished, with some evidence of introgression. The study also identified a distinct genetic group of cultivated walnuts, mainly composed of the popular 'Yangbidapao' landrace.
