According to Griffing's method 1, diallel crossing was built and CA was analyzed. Variance analysis showed that there were the greatly significant difference among the both of GCA in inbreeds and SCA in crosses, respectively. The high GCA of 18-599 and 18-599 and the low SCA variance of their crosses showed the strong and stable heredity on the both characters. Taking them as parents, the generations with high and stable induction and regeneration will be gotten.
