【摘要】 本试验以6个芥蓝自交系为材料,按照6×6完全双列杂交,得到36个组合。并对其硫苷组分的配合力和主要遗传参数进行了分析。结果表明:P₁、P₂和P₅的GCA综合效应表现优良,利用这三个亲本配置组合可以有效提高芥蓝后代抗癌硫苷成分的含量:从组合的SCA效应分析得出,1×2属于综合优秀的组合。通过主要遗传参数分析,芥蓝中硫苷成分的广义遗传力普遍较高.狭义遗传力普遍较低,杂种优势利用潜力较大。更多还原

【Abstract】 The study was carried out with six Chinese kale lines as material.Complete diallel crossing was designed with 6×6 to calculate the combining ability and the main genetic parameters.The results are as follows:The GCA effect of P₁,P₂ and P₅ was excellent.They were used as parants to get hybrids,the heterosis of anti-cancer glucosinolates of their hybrid was very high.By analyzing the SCA effects,1×2 was an outstanding hybrid.The broad sense heritability of the main GSs were relatively higher,and the narrow sense heritability were lower,so the potential of heterosis was bigger.更多还原
