| Abstract: | High photosynthetic efficiency germplasm is the basis for the high photosynthetic efficiency breeding of crops. Based on the analysis of the requirements, despite the difficulties and research deficiencies of high photosynthetic efficiency germplasm screening in rape, our research team constructed a comprehensive screening index system and method for rape with high photosynthetic efficiency to meet the breeding objectives of super high yield rape and the practical production demand. Quantitative comprehensive evaluation of rape germplasm was conducted and directional breeding and crossbreeding improvement was developed. Practical application achieved good results and a number of high photosynthetic efficiency germplasms were obtained, which laid a material foundation for rape breeding with high photosynthetic efficiency by a way called high photosynthetic efficiency + heterosis. |
