Abstract:
High yield variety of soybean is not only a variety of high yield per plant，but also a variety with tolerance to solid-planted.The purpose of this study was to achieve variety with tolerance to solid-planted.By using 10 soybean varieties(lines) including two kinds of leaf shape，from the aspect of the marginal effect index，the marginal effect index and their relationships between leaf traits and yield traits of soybean varieties were measured or calculated.The results showed that the marginal effect index of long leaf soybean cultivars was smaller than that of round leaf soybean cultivars，including leaf length，leaf width，leaf area，pod number per plant，seed number per plant and 100-seed weight.These varieties were suitable for dense planting.The marginal effect index of yield per plant was not significantly correlated to that of leaf traits.It was very significantly correlated to that of pod number per plant and seed number per plant and significantly negatively correlated to that of 100-seed weight.The marginal effect index of yield per plant of Suinong14 was the smallest among all soybean varieties with tolerance to solid-planted.
