Abstract: Analysis was conducted on major agronomic characters and yield at 15 spring soybean varieties and 14 summer soybean varieties with multivariate statistic method. The results showed that Seeds per plant, 100-seed weight and plant height of spring soybean were more important direct impact on yield, and three factors were considered first in breeding. Pods per plant and seed weight per plant of summer soybean were more important direct impact on yield and seeds per plant had extremely significantly positive relation with yield per plant. So selective effect based on three characters was finer. The breeding should pay attention to the balance between the various characters, we should think about the various agronomic characters of soybean exists the mutual influence at each other at the same time.
