利用自交不親和性育成甘藍之一代雜種

The Utilization of Self-incompatibility to Breed F1 Hybrid Cabbage

由分離之8品種13系統甘藍為材料，利用自交不親和性以育成F1甘藍，在116試交組合中選出3優秀組合，合乎育種目標，具高溫結球性，早生，耐病及品質良好之性質。其中有兩組合具相同之一親本，此親本花苔較低而花及種子產量較少，採種時，必須設法解決此系統之抽苔開花問題。另一組合係品種內系統間交配，且親和性，抽苔開花很正常，且均已達自交不親和性。

1. In order to have a variety of cabbage for Taiwan summer growing. Thirteen strains of eight varieties cabbage were used for materials Utilization of self-incompatibility in the production of F1 hybrid cabbage. 2. Selected S combinations among the 116 cross combinations, which had hot hardiness, early maturity disease resistance and good quality. 3. But two these combinations are same one of parents it can't stalking and flowering completly, unless deeper and longer of low temperature. The other combination is crossing between strains of a variety, its attained self-incompatibility and cross-compatibility already.
