| 摘 要： | 研究表明，基部挫折重、光合速率、生物产量等性状对水稻倒伏指数具有较大的负效应，株高、鲜重等性状则具有较大的正效应，其中以基部挫折重的直接作用最大。按基部挫折重大，光合速率和生物产量高的方向选择，有利于抗倒伏性和产量性状的改良。

| Abstract: | The results of this study showed tlat the characters of the basal setback weight, photosynthetic rate and biological yield had negative effects on the lodging index of rice, but tte plant weight and fresh weight had the positive effects Among the characters mentioned above, the basal setback weight played leading direct roles It was proposed that the selection of higher basal setback weight, photosynthetic rate and biological yield was benificial to the breeding of rice varieties with high lodging resistance and yield |
