大白菜与7种芸苔属植物种间杂交亲和力的研究

Studies on the Hybridized Combinations Affinity between Chinese Cabbage and 7 Species of Brassica Plants

本试验对大白菜与其它7种(13个品种)芸苔属植物种间杂交亲和力进行了初步研究。共配制25个正、反交组合。对各组合的杂交结角率、结籽率、亲和指数进行了调查,结果表明这七种芸苔属植物与大白菜杂交结角率高、结籽率高、亲和能力强的是青菜(B.chinensis L)、芜菁(B.chinonsis L)、甘兰型油菜(B.napus L);杂交结角率、结籽率低,亲和能力弱的是芥菜(包括芥菜型油菜(B.juncea (L)Coss)、白芥(B.alpa Boiss)、阿比西尼亚油菜(B.carinata Braun)和甘兰(B.oleracla L)。据此,对大白菜繁种生产中隔离区的设置提出了建议。

A preliminary study is carried out on the hybridized combinations affinity between Chinese cabbage (B. pekinesis Rupr.) and 7 species (B. varieties) of Brassica plants in this experiment. 25 hybridized and reverse hybridired combinations have been made to which that have been tested respectively, ratios of pod-setting and seed-setting, affinity index. The result shows that, among these species, followed plants combined with Chinese cabbage have higher ratios of pod-setting and seed-setting and strong affinity, pickled cabbage(B, chinensis L.), while those plants combined with chinese cabbage have lower ratios of pod-setting and seed-setting less affinity or no affinity: leaf mustard (B.juncea Coss.), white mustard (B. alba Boiss.), Ethtopian rape (B. carinata Braun)and cabbage(B. oleracea L.); According that above, a proposal is put up about setting up isolated plot in the seed reproduction of Chinese cabbage.
