摘要: Studies for many years have indicated that the seed yield of (Glycine max L. Merr.) soybean can be increased by increasing photosynthetic efficiency. The yield of cultivars with high photosynthetic efficiency (HPE) increased by 30%-40% in comparison with the cultivars with normal photosynthetic efficiency, indicating that the breeding of soybean by increasing HPE may have a bright prospect. HPE breeding can be used as the temporal monitoring in the breeding process to avoid the divergency of the predetermined goal, although HPE breeding does not shorten the breeding time. It was observed that limited C_4 pathway exists in soybean leaf and pod, suggesting that by increasing the genetic expression of some C_4 enzymes in C_3 crops through traditional or genetic engineering techniques, new breakthroughs in increasing the photosynthetic efficiency of C_3 plant may be practicable in the future.
