摘要
用远缘杂交的方法 ,对南瓜属中的 4种南瓜进行相互杂交 ,观察其间的亲和性及 F1 、BC1 代的植物学性状表现。结果表明 ,通过蕾期和花期重复授粉、混合授粉获得的远缘杂交后代具有杂种优势 ,植物学性状亦有变异 。
The wide cross compatible was used to cross the four species in curcubita genus and the expression of botanical traits in F 1 and BC 1 progeny of them were study in 1998～2000.The results showed that the F 1 hybrid among them can be got by repeatation.Pollination at bud and flowering stage.The F 1 plants had heterosis in growth ability and disease resintance and wide variation in botanical traits.There are metaxemia on taste of flesh and the color of pumpkin.
