In this paper, the physiological and biochemical characteristics of cotton heterosis expressed at home and abroad are reviewed. Cotton hybrids mainly show the following advantages: photosynthetic productivity, endogenous hormone metabolism, isozyme expression advantage. In the future, the ways of physiological and biochemical research on cotton heterosis were put forward, and some suggestions for reference were made.
