Abstract:
The stepwise regression method was used to study the relation between major agronomy characters and yield of 26 varieties which included 23 reliesed varieties in Henan Province.The study showed that around 110.5 day growing stage,0 scare SMV,less than 0.7 scare lodging,more than 54.2 pods per plant,around 27.9 g weight per 100 seeds and 0% rate of purple spot were best indexes to increase the yield in the future.The soybean yield could be 71.8% higher than the check variety if the best indexes were used.
Key words:
