- Abstract:
- Six soybean varieties from different ecological region were selected and made 9 hybrid combinations according to NC II mating design.Genetic effect and heterosis of several agronomic traits under different ecological environments were analyzed by the models of genetic effects and genotype×environment interaction for additive-dominant epitasis.The results showed as follows(i)Dominant effect of all researched agronomic traits were significant,selecting and using heterosis of them were affected by environment to a certain extent.(ii)Broadsense heritability（BSH） were significant over 0.05 level for all tested traits.Seed weight per plant had highest BSH,which was suitable for selection in higher generation.The interaction of BSH between branch number and pods per plant were significant at 0.01 level.(iii)Heterosis of 100-seed weight was more stable than other traits in different environments.Heterosis of tested traits in Harbin were more obvious than the other three sites.Yield-related traits exhibited certain heterosis,the high-parent heterosis for configuration traits was not obvious.
