利用分子标记创制新型不育系,根据双亲遗传差异确定优势群,定向设计优势组合,是目前杂交油菜最先进的育种技术。“浙核杂”系列油菜杂交组合所用不育系是通过分子标记辅助下的连续回交,将2个不育基因导入浙江省主栽品种浙双72、浙油50而成,株型、结实性和抗逆性等综合性状较好,这是选育出较高水平杂交油菜的基础。“浙核 The use of molecular markers to create a new type of sterile line, according to the genetic differences between parents to determine the dominant group, the advantages of directional design combination is the most advanced rapeseed breeding technology. The sterile lines used in the crosses of rapeseed series ”Zheganza“ were introduced into the Zhenshan 72 and Zheyou 50 Zhejiang cultivars through continuous backcross assisted by molecular markers. , Good comprehensive traits such as firmness and resistance, which is the basis of breeding higher rapeseeds. ”Zhejiang nuclear
