The Research Progress and Prospect of Cold Resistant Breeding of Tropical Crops in China
The tropical regions in China are located in the northern margin of tropical areas, thus often suffered from cold damage. Chilling injury has become one of the most serious adverse factors influencing the healthy and stable development of tropical crops in China. Actively carrying out cold resistant breeding of tropical crops and breeding high yield varieties with cold resistance have become a fundamental guarantee for tropical crops development in China. From the aspects of cold resistant germplasm collection, cold resistant varieties breeding and the progress of cold resistant mechanism, the paper discussed the research progress and research results of cold resistance variety breeding. Finally it pointed out the current problems existing in cold resistant breeding of main tropical crops, and discussed the future development trend in our country.
