以３５个春大豆品种（系）为材料，研究了各主要农艺性状春播和秋播间的相关关系．结果表明，春大豆主要农艺性状如株高、单株粒数、主茎节数、每荚粒数、有效分枝、总荚数、有效荚数、营养生长期和全生育期等性状在春播和秋播间存在着显著或极显著的相关．表明秋播条件下对这些主要农艺性状的选择效果较好，而对单株产量、百粒重等性状的选择效果不佳．
Using 35 spring soybean varieties (lines) as materials, the correlations between spring sowing and autumn sowing of each major agronomic traits were studied. The results showed that main agronomic characters of spring soybean such as plant height, number of per plant, number of main stem, number of per stem, effective branches, total pods, effective pods, vegetative growth period and full growth period There was a significant or significant correlation between autumn and autumn. The results showed that the selection of these main agronomic traits was better under the conditions of autumn sowing, while the selection of traits such as per plant yield and 100-grain weight was not good.
