Raising method of floral-leaf Chinese cabbage hybrid with male sterile line

The raising method of floral-leaf Chinese cabbage hybrid with male sterile line includes: transfer raising male sterile line to obtain floral-leaf Chinese cabbage male sterile line with sterile plant rate and sterile degree of 100 %; screening out several male sterile lines with different target characteristics based on the characteristics of the transferred materials and compounding hybrid combination with these male sterile lines as female parent and complementary selfing line male parent; and final field identification, variety comparison and production test to obtain new hybrid with the target characteristic. The present invention has the advantages of greatly raised seed quality, no plagiarism of the bred male sterile line, strengthened activity of the parents, and low seed cost. 一种利用雄性不育系培育青麻叶大白菜杂交种的方法，其特征在于：①首先要进行雄性不育系的转育，得到不育株率和不育度均为100％的青麻叶类型雄性不育系；②然后根据各个转育材料的性状特点，筛选出多个具有不同目标性状的雄性不育系，再以这些雄性不育系为母本，根据互补的原则配以相应自交系父本配制杂交组合；③最后经过田间鉴定、品比试验和生产试验等过程，获得具有目标性状的新的杂交种。本发明的优点是：1.种子质量得到大大提高。2.育成的雄性不育系在生产制种过程中不会被剽窃。3.避免了亲本生活力衰退，使其活力大大增强。4.种子成本降低80％以上，提高了市场竞争力。
