选育双低甘蓝型杂交油菜是克服优质油菜品质与产量矛盾的重要途径。本研究从1980年开始向双高细胞质雄性不育“三系”导入“双低”基因,建立了恢、保性状与品质性状同步筛选程序,育成了5个配套的双低雄性不育“三系”,强优势组合产量接近秦油2号水平。
Breeding double low-yielding Brassica napus is an important way to overcome the contradiction between quality and yield of high-quality rape. In this study, the “double low” gene was introduced into the “three lines” of double high cytoplasmic male sterility from 1980, and a simultaneous screening program was established to restore sexual traits and qualities traits. Five pairs of male sterile lines Department ", the output of strong superiority is close to the level of Qinyou No.2.
