Abstract: In this paper, two new kinds of crop yield potentials, the inherent and the extrinsic, were put forwarded. Based on the analysis of food production situation in China, the importance of enhancing crop’s yield potential was stressed. It was introduced that researching of yield potential of cultivar, progress of genetic improvement and photosynthetic characters were investigated and researched systematically, the approaches on how to enhance yield potential of cultivar were summary. At last, the facing difficulties and outlet of studying yield potential in China was brought forward.
