摘　　要：选取四川省有代表性的１７份春、夏、秋大豆品种，进行春、夏、秋分季播种试验，对产量、生育期及其它农艺性状进行稳定性分析．结果表明：西豆３号和筠连七转豆的出苗至始花日数，９０－６２７和８４０７－１的出苗至成熟日数，９０－６２７和９０－３的产量，贡豆９１－１的株高，成豆四号、西豆３号、９０－３的单荚粒数，以及９０－６２７的百粒重等性状在春、夏、秋不同播季下均比较稳定，对光温敏感性弱，可作为生产利用和育种亲本材料．We select 17 typical varieties of Spring, Summer and Autumn soybeans in Sichuan province and make planting experiments on them respectively. On the basis of experiments, we adopt stability analysis method, the result shows that the days from the emergence of seedling to the beginning of florescence of Xi Dou 3 and Jun Lian 7 Zhuan Dou, the days from the emergence of seedling to maturity of 90-627 and 8407-1, the yield of 90-627 and 90-3, the plant height of Gong Dou 91-1, the grains per pod of Cheng Dou 4, Xi Dou 3, Gong Dou 5 and 90-3, and the weight per 100-grains of 90-627 are stable in Spring, Summer and Autumn sowing seasons. That is to say, the above traits of these varieties are not very sensitive to photoperiod and temperature. This can provide producing and breeding with reference.
