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
