- Abstract
Seed vigor is a crucial indicator comprehensively assessing the quality of seeds, reflecting the growth advantage and production potential of seeds, and has a significant effect on seeds' stress resistance. Identifying and controlling loci related to wheat seed vigor is essential for accelerating genetic trait gains. Here, we performed a large genome-wide association study (GWAS) to identify several significant quantitative trait loci (QTLs) associated with seed vigor-related traits. A total of 404 wheat samples with diverse genetic backgrounds were used as experimental materials. Twenty-eight loci significantly associated with seed vigor-related traits in wheat were identified, distributed on chromosomes 3A, 4A, 5B, 7A, and 7B. Two potential novel loci controlling wheat seed vigor were discovered, with a total of 80 candidate genes associated with seed vigor located on these loci. Among them, TraesCS4A01G020000.1 encodes a late embryogenesis abundant (LEA) protein gene, and TraesCS5B01G298500.1 encodes a helicase gene, both showing specific expression in seeds and highly correlated with seed vigor. Overall, these findings provide valuable insights for the future application of these genes in wheat breeding.
