Abstract：Ten hybrid combinations were obtained from 5 Chinese kale（Brassica alboglabra Bailey）inbred lines with better productive performance and significant different traits by Griffing incomplete double-row crossing design．Combining ability analysis was conducted on 8 economic traits，and genetic parameter analysis was carried out on 5 economic traits with significant difference．The results show that the 5 economic traits are affected by the additive and non-additive effects．Among them the quality and thickness of carex dispalatha and leaf width are mainly controlled by gene additive effect，the quality of single plant is controlled at the same time by dominant and additive effects，while the internodes length is controlled mainly by dominant effect．By comprehensive comparison between 5 inbred hybrid offspring performances of Chinese kale，we find parent strain A（0925）and parent strain D（0948）have high general combining ability（GCA）．Its distribution group is expected to gain the highest F1 offspring with special combining ability（SCA），but the special combining ability between parents should be considered in the selection．
