黔油2AB是从全国双低名优品种——油研2 号中发现的可遗传不育突变体,采取田间选择与室内品质筛选有机结合的方法,通过连续优异不育株与可育株兄妹交保持选择,定向培育而成的甘蓝型双低细胞核显性雄性不育系,其芥酸含量低于1% ,硫苷含量低于30 μm ol/g,含油量高于40% ;其育性分明,不育性彻底,且不受环境影响;田间长势强,经济性状好,菌核病发生较轻,配合力好。具有较好的研究利用前景。 Qianyou 2AB is a heritable male sterility mutant found in the double-low-breed, Yanyan No.2 in China. The method of organic combination of field selection and indoor quality screening was adopted. Through continuous elite sterile plants and fertile plants Maintaining the selective and directional cultivation of Brassica napus male sterile lines with less than 1% erucic acid, less than 30 μmol / g glucosinolate and more than 40% oil content, the fertility Clear, sterile and complete, and not affected by the environment; Field grow strong, good economic traits, sclerotialis occurred lighter, with good. Has a good prospect of research and utilization.
