摘要:

近年,直播稻面积在我国迅速扩大。本文结合国内外直播稻生产概况,指出了直播稻在抗倒伏、出苗率、耐冷性、防治杂草以及生育期等方面存在的问题,提出了培育“生育期适中、抗倒伏、耐低温、耐低氧萌发”的适合直播的水稻新品种选育策略。

关键词: 直播稻, 品种选育, 低氧萌发, 遗传改良

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.

Key words: direct seeding rice, variety breeding, anaerobic germination, genetic improvement
