| 摘 要： | 以重庆市10个春大豆品种为材料,通过分季播种,研究了各主要农艺性状在春播、夏播和秋播间的相关关系。结果表明:春大豆农艺性状如营养生长期、株高、主茎分枝数等在春播和夏播条件下存在显著或极显著相关;主茎分枝数、单株产量、营养生长期、百粒重在春播和秋播条件下存在显著或极显著相关;表明在夏播、秋播条件下进行春大豆育种对这些主要农艺性状的选择效果较好,而对其他性状的选择效果不佳。

| Abstract: | Ten spring soybean varieties widely cultivated in Chongqing were sown on different dates in spring,summer and autumn.Significant or highly significant correlation was found to exist between the spring-sown and summer-sown crops in the agronomic characters of vegetative growth period duration,plant height and branch number of the main stem,and between spring sown and autumn-sown crops in the agronomic characters of branch number of the main stem,yield per plant,vegetative growth period duration and 100-seed-weight,thus suggesting that selection of spring varieties of soybean for the above-stated characters in the summer-or autumn-sown is feasible. |
