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著水准，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。
Ten combining ability and the genetic effects of main agronomic characters of new released male steral lines A 2F 4A,A 1356A 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 A 2F 4 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.
