摘要: 以国外引进的花椰菜雄性不育系MSA为不育源,与青花菜自交可育系杂交。通过回交转育,将花椰菜胞质雄性不育系转为青花菜胞质雄性不育系,经过1代杂交,4代回交,选育出遗传性稳定,不育株率和不育度均为100%,园艺性状优良的不育系5A。Abstract: Cauliflower male-sterile line MSA was used as sterile source, crossed the breeds with broccoli ferbile line.And through back-crossing bred,cauliflower cytoplasmic male sterile line was transfered to broccoli cytoplasmic male sterile line.After one-gerenation crossed and four-gerenation back-gerenation back-crossed, an exeellent horticulture character sterile line 5A was selected, where genetic character was stable, and the percentage of stage plant and the sterility percentage were 100%.
