Firstly, 66S was bred through multi -generation oriented breeding of ecotypic dual -purpose rapeseed male sterile line 501-8S, which was bred by Agricultural Sciences Research Institute of Yichun City in Jiangxi Province .Then, 66S was hy-bridized with early-maturing high-quality hybrid rapeseed variety Qingza 3, the bagging selfings of their 6 hybrid generations were conducted for 3 years, their fertilities were identified , and their qualities were analyzed .Finally, early-maturing ecotypic dual -purpose rapeseed male sterile line 6S was bred.The new variety 6S has the characteristics of early maturing , good quality, and sta-ble fertility conversion , and it can be used to make up two -line early-maturing hybrid rapeseed new combinations .
