摘 要 ：高粱茎秆汁液中乌头酸的含量受两组基因控制。基因的分布频率不均衡。一般配合力方差是特殊配合力方差的11.62～12.23倍。狭义遗传力为44.18～48.68%。T×622、T×624和 T×390的一般配合力效应值较高;T×378、4692A、榆5A、1729A、7501A、7502A、7504A 和7718A 的效应值较低。由于该性状的遗传力较低,应该在较晚世代进行选择

Abstract:Aconitic acid content in sorghum stem juice was controlled by 2group genes,Frequency of gene distribution was unbalanced.Variancesof GCA were 11.62～12.23 times that of SCA Narrow herita-bility was 44.18～48.68%.Effect values of GCA of Tx622 Tx624and Tx390 were higher than that of Tx378,4692A,yu-5A
