The current research deficiency was analyzed from the aspects of obtaining high photosynthetic efficiency germplasm， accurate identification of high efficiency phenotype， evaluation index， breeding value， and breeding mea and with our work for yea， we propose 8 ways for improving the screening of high photosynthetic efficiency germplasm of crop， including strengthening research on the photosynthetic mechanism of crops， broadening the screening scope， creating high photosynthetic efficiency germplasm by molecular polymerization technology， cotructing fast and accurate determination method of high photosynthetic efficiency phenotype， creating compreheive screening index system， improving the utility efficiency， establishing germplasm resources innovation system and sharing platform， and strengthening the breeding technology。 Keyword：　high photosynthetic-efficiency germplasm; screening effect; research deficiency; solution strategy; 0、 引言 作物积累的有机物质95%左右来自于光合作用， 光合作用的强弱和效率的高低直接决定着到作物的产量， 因此高光效育种一直都是作物光合研究和育种领域关注的热点。经过多年努力， 国内外研究者在水稻、大豆、小麦等作物上已选育出一批高光效品种 (系) :如‘黑农41
