苦瓜强雌系屿强-2的选育及利用

Breeding and Application of Bitter Gourd Pistillate Line,Yuqiang-2

屿强-2是从南屿苦瓜中选育出的苦瓜强雌系,单株主蔓雌花率90%,强雌株率90%。利用屿强-2配制4个杂交组合,以南屿苦瓜作对照进行比较。结果表明,149组合产量比对照减产5.7%,148,172,135三个组合都有不同程度的增产,幅度在7.1%~19.6%。利用屿强-2小面积制种纯度达100%。

＂Yuqiang-2＂ is a bitter gourd pistillate line selectively breeding from ＂Nanyu＂.The pistillate flowers rate from its main trail is 90% and its plant rate is up to 90% also.Judging from four different crossing combinations by Yuqiang-2,the result shows that one of the combination yield is 5.7% less than the contrast,while the other three combinations are more than the contrast,ranging from 7.1%-19.6%,compared with Nanyu.The purity is 100%,the purity of the seeds produced by the small-scaled plantation using Yuqiang-2 can be as high as 100%.
