Abstract
In order to investigate changes of yield,harvest index,biomass,seed fat content and seed protein content,sixteen soybean cultivars planted popularly under field trial were studied in Jilin province.The result indicated that biomass of soybean cultivars increased to a maximum around R6 and then declined.Biomassof old cultivars declined faster than the modern ones.The modern cultivars had greater biomass than old ones.Biomass,seed yield and harvest index increased with the year of released.The annual yield improvement was 14.90kg·hm-2,and the annual harvest index increased 0.23%.The fat content levels increased(0.04%) accompanied by seed protein content reduce(0.06%) with the year of released.The increase in seed yield was significantly correlated with the increase of HI and biomass.However,positive correlation with seed fat content and negative correlation with seed protein content,were not unobvious.The results show genetic improvement of soybean yield had led to biomass and harvest index increase.Biomass and HI can be considered as two important indexes to improve soybean yield.
