| Abstract: | In recent years, the area of direct seeding rice has expanded rapidly in China. Combining with the production situation of direct seeding rice at home and abroad, the problems of direct seeding rice in lodging resistance, seedling emergence rate, cold tolerance, weed control and growth period were pointed out, and the breeding strategies of new rice varieties suitable for direct seeding with “moderate growth period, lodging resistance, low temperature tolerance and anaerobic germination tolerance” were put forward. |
