High-density whole-genome resequencing unravels the genetic basis of yield components in alfalfa via multi-environment GWAS
Alfalfa (Medicago sativa L.) yield is a complex quantitative trait shaped by multiple yield components and strong genotype-by-environment interactions. In this study, we combined multi-environment phenotyping with deep whole-genome resequencing to dissect the genetic architecture of six agronomic traits in 198 half-s...
