Rapeseed is a major oilseed crop in China, and enhancing rapeseed yield represent a key goal for breeding programs. Among the three rapeseed main yield components, 1000-seed weight (TSW) is a pivotal factor. The high-yield hybrid variety ‘Dadi199’ is one of the most widely planted cultivars in China, with a very high TSW. In this study, we evaluated the TSW of a doubled haploid population (ZRDH) containing 280 lines derived from Dadi199 across four distinct environments, with the objective of de
