| Abstract: | A comprehensive analysis of national main rice varieties approval status and planting area in 1985-2015 was conducted. The result showed: (1) the number of approved rice varieties continues to grow rapidly, (2) the number and area of both main cultivated cultivars and dominant varieties were decreasing, (3) the concentration degree of variety decreased significantly, (4) the development of the conventional rice varied in different regions, while hybrid rice has achieved rapid development nationwide. The factors affecting the quantity, distribution and structure of rice varieties were analyzed, and issues on breeding and popularization of rice varieties were discussed. |
