Abstract:
The relationship between yield and several chief characters were studied by using two soybean cultivars which have high yield potential under different population. The result showed that the differences influenced by plant rate between both genetic types including ratio between plant height and stem diameter，leaf area index，leaf area duration，dry matter accumulation and yield were apparent. The correlation coefficients of yield with the leaf area index were tending to positive at V3 and R1, and was significant at R3，R5 and R6.The correlation coefficients of yield with leaf area duration were tending to positive at V4～R1、R1～R3 and R5～R6;the correlation coefficients of yield with the dry matter accumulation were tending to positive at R3, and was significant at R5.The result also indicated that at laterstage the population of KJ21 still maintained high leaf area index and dry matter accumulation,which would benefit for high population densities.
