Abstract:
8 varieties with the same growth habit were used in this experiment , among of them Hs93 -4118 ,OhioFG1,Darby and Kottman 4 American soybean varieties are from Ohio State University ;and 4Chinese soybean varieties Liaodou - 11 , Liaodou - 12, Shennong 94 - 11and Shendou - 4 are from Liaoningprovince. Under same conditions, the plant - type and yield were compared among the 8 soybean varieties.The results show that the plant height of American soybean varieties is lower than that of Chinese varie-ties, the branch number of American soybean varieties are significantly more than those of Chinese soybeanvarieties, the length of basal nodes of American varieties is longer than that of Chinese varieties. Thelength of nodes become shorter with the rising of node - position, the leaf shape index of American varie-ties is bigger than those of Chinese varieties at the lower layer , the leaf shape index of American varietiesbecome bigger from lower layer to upper layer ,the top leaves of American varieties are small and sharp ,which would benefit the leaves productivity at the bottom of plant. The pods per plant of American varie-ties are bigger than those of Chinese varieties, the 100 - seed weight of American varieties is smaller thanthat of Chinese varieties significantly. The ratio of seed weight at upper canopy layer of American varietiesis smaller and the ratio of seed weight at lower canopy layer is bigger than those of Chinese varieties, theyield of American varieties is higher than that of Chinese varieties.
