摘要: 用不完全双列杂交方法,对新选不育系F4A、356A及目前生产上常用的3个不育系9个恢复系进行了配合力及遗传效应的分析。株高、穗长、穗茎粗、开花期、穗重、穗粒重、穗粒数和千粒重等8个性状的分析结果表明,所有亲本各性状配合力方差均达到极显着水准,在全部被研究性状的遗传控制中,加性基因效应占主导地位。5个不育系中,A2F4A在全部8个性状上的一般配合力效应值最高;恢复系8643变在株高、穗重、穗粒重和开花期上具有较高的一般配合力效应值。

Abstract: Ten combining ability and the genetic effects of main agronomic characters of new released male steral lines A2F4A,A1356A and three commercial A lines as well as their hybrids from nine R lines was analysed.The results indicated that the combining variance was significant in plant height,panicle length,days to 50% flowering,panicle weight,grain weight per panicle,number of grains per panicle,1000 grain weight.Genetic analysis showed that additive effect was prominent in the character inheritance.GCA effects of A2F4 were significantly higher than other male sterile lines in all 8 characters.GCA was significantly higher than other restorer lines effects of R line 8643 on the plant heitht,grain weight per ear and days to 50% flowering.
