| Abstract:In order to promote advance of rape high photosynthetic efficiency breeding,based on analysis of difficulties,research defects and favorable conditions,and for the breeding objective of super high yield breeding and actual demand for rapeseed production,different solutions and methods such as multi-channel creation of the Brassica napus germplasm,broad screening range of high photosynthetic efficiency germplasm were proposed.Comprehensive evaluation index system was established for identifying,improving and increasing the actual efficiency of high photosynthetic efficiency germplasm; rape index system of high photosynthetic efficiency structure was also built for increasing photosynthetic efficiency of groups,the fast and efficient hybrid method system of high photosynthetic efficiency breeding were established by using different ways.The breeding efficiency was improved by carrying out molecular design breeding of high photosynthetic efficiency.Cultivation of rape high photosynthetic efficiency was studied and applied for solutions to promote consistent photosynthetic capacity. |
