青花菜雄性不育系选育研究初报

Preliminary study on breeding of broccoli male sterile line

以具有细胞质雄性不育基因的青花菜不育材料CMS94008为不育源,通过杂交和连续回交的方法选育出不育性稳定、经济性状良好的一批青花菜胞质雄性不育系,并以CMS92100、CMS93-2、CMS9905、CMS95234等不育材料及其转育父本为代表,对不育系的主要特征及农艺性状进行系统的观察鉴定。

Broccoli male sterile material CMS 94008 was used as sterile source. Through cross-breeding and continuous back-cross breeding, broccoli cytoplasmic male sterile (CMS) lines with stable sterility and good commercial characters were bred. Taking CMS92100, CMS93-2,CMS9905,CMS9905, CMS95234 and their male parents as samples, the morphological characters and agronomical characters of sterile lines were described.
