摘要
[目的]利用水稻多倍体自交回复创制优良二倍体育种材料.[方法]同源多倍体自交回复后代中出现二倍体植株,在其分离后代中,通过系统选择,选择其中稳定的优良二倍体材料与三系、两系不育系进行广泛测交配组,对具有较强杂种优势的水稻进行考种.[结果]Y58S/10-C242、Y58S/10-C256、C815S/12-C156、C815S/13-C96的杂种一代具有一定的杂种优势.[结论]多倍体自交回复后代中的优良二倍体植株可为杂交稻选育提供优良亲本材料.
Abstract
[Objective] To develop excellent diploid rice breeding materials by using autopolyploid self returning.[Method] The diploid plants appears in the later generation of autopolyploid self returning.Excellent diploid materials were selected to test cross with sterility lines through the system selection in segregating progeny.Then we checked the rice seed with heterosis.[Result]There had heterosisy in the first generation of hybrid of Y58S/10-C242,Y58S/10-C256,C815S/12-C156,C815S/13-C96.[Conclusion] Excellent diploid plants can Provide good parent materials for hybrid rice breeding.
