Abstract:: The study adopted 24 soybean cultivars(lines) to investigate the correlation between the growth stage，main agronomic characters and yield.The results indicated that the yield correlated positively and significantly with the V3-R2、R4-R6 growth stage，negatively with the R2-R4 growth stage.The yield had significant correlation with plant height，branch number of main stem，pod number per plant，grain number per pod.The path coefficient analysis showed that pod number per plant contributed to yield mostly，then was stem diameter and 100-seed weight.Through cluster analysis，the results indicated that the materials could be classified into 4 groups.Each group had it’s obvious features，and the Ⅳ group is suitable for relay-planting condition
