摘　　要：对不同春小麦品种及其后代中光合速率遗传规律研究,结果表明:小麦光合速率属于数量性状遗传,通过品种间杂交,能够选育出光合速率较高的后代材料。F2中光合速率类型多样,是高光效育种中重要的选择世代。The study on photosynthetic rates and genetic laws of hybrid offspring for different spring wheat varieties was done. The results showed that photosynthetic rates of wheat belonged to quantitative character inheritance. Through cross-fertilize between varieties, the higher photosynthetic rate of the hybrid offspring can be bred. It was important in high photosynthetic efficiency breeding selection from generation to generation of various types of photosynthetic rate in the F2 generation.
