摘    要:通过采用花期和蕾期喷5%NaCl溶液的方法,提高大白菜授粉后花期亲和指数,以期解决大白菜多代自交后结实指数降低的问题。结果表明:喷施NaCl溶液对自交不亲和系、正在选育中的自交不亲和系的株系及稳定的自交系,均可提高其花期自交的亲和指数,尤其对自交不亲和系(4号株系)提高程度更大,差异极显著;该方法对降低大白菜自交不亲和系的种子生产成本效果明显,在大白菜杂种优势育种方面有重要的应用价值。

关 键 词:NaCl溶液  大白菜  自交不亲和系  亲和指数

Abstract:Aiming at the decreasing fructification index of multi-generation selfing cabbages,the solution of 5%NaCl to improve their flowering affinity index was used,thus to reduce the costs of self-incompatible cabbage seed.The results showed that the use NaCl could increase the flowering affinity index of self incompatibility lines and inbred lines,especially could improve the fourth.It’s abvious to cut the costly on production of seed of self incompatibility lines.
Keywords:NaCl  Chinese cabbage  self-incompatibility system  self-affinity index
