摘要： 以大白菜小孢子植株再生能力不同的材料为亲本,采用双列杂交方法,研究了小孢子植株再生能力的遗传特性。大白菜小孢子植株再生能力的遗传符合加性-显性模式,主要受核基因控制,基因作用以加性效应为主,高植株再生能力由隐性基因控制,狭义遗传力为70.6%。

Abstract: Inheritance of plantlet regeneration ability of microspore-derived embryos was examined by 4×4 diallel crosses.Diallel analyses showed that the inheritance of plantlet regeneration ability of microspore-derived embryos fitted to the "Additive-dominant Model" and was mainly controlled by nuclear genes.The additive genetic effects were largely contributed to the genetic variance.High plantlet regeneration ability was controlled by recessive genes.The narrow sense heritability was 70.6%.
