摘要
Abstract
Inheritance of microspo re embryogenic ability in B.napus wasexamined by 4×4 diallel crosses using 2 high responsive cultivars (`Topas' and `Lisandra') and 2 low and no res ponsive ones (`Kizakino' and `Kamikita').Most of F1 hybrids showed that embryo yields similar to the high responsive parent and some showed embryo yields simi lar to the mid-parent value.Diallel analyses showed that both additive and domi nant effects were significant at 1% level in the genetic control of microspore e mbryogenic ability.Additive gene effects were predominant.High embryogenic abili ty was controlled by dominant nuclear genes.The broad-and narrow-sense heritabil ities were 97.2％ and 81.1％,respectively.From the results of segregation of e mbryo yields in F2 population of`Lisandra'×`Kamikita',it is concluded that th e microspore embryogenic ability was controlled by two loci with additive effects.关键词
