早籼型不育系351A的配合力研究

Research of combining ability of early indica sterile line 351A

３５１Ａ与珍汕９７Ａ、协青早Ａ、４７Ａ的一般配合力效应均不显著。珍汕９７Ａ、协青早Ａ的一般配合力高，是配制迟熟杂交稻组合的主体不育系。３５１Ａ的特殊配合力和早熟遗传强，是配制早稻、早熟中稻杂交组合的优良不育系。

The general combining ability of 351A is not significant compared with Zheng shan 97A and Xieqinzao A and 47A.The general combining ability of Zheng shan97A and Xieqin Zao A is high .They are main sterile lines for breeding of late hybrid rice combinations.The special combining ability and early hereditary capacity of 351A is strong.It is good sterile line for early rice and early middle hybrid rice combinations.
