摘要
我国是水稻生产大国,也是消费大国。新中国成立70多年来,我国的水稻事业取得了显著发展,特别是杂交水稻的发明为我国的粮食安全提供了坚强保障。在当前粮食生产减少农药、化肥施用的"双减"目标新形式下,培育高产、优质、抗逆和广适应性的水稻新品种势在必行。笔者就高抗稻瘟病恢复系明恢63及几个抗飞虱恢复系的育种实践向大家做介绍。
China is a big producer and a big consumer of rice. Over the past 70 years since the founding of the People’s Republic of China, China’s rice industry has made remarkable progress, especially the invention of hybrid rice has provided a strong guarantee for China’s grain stability. Under the current new goal of reducing pesticide and chemical fertilizer application in grain production, it is imperative to cultivate new rice varieties with high yield, high quality, strong resistance and wide adaptability. The author introduced the breeding practices of the rice blast-resistant restorer line Minghui 63 and several planthopper-resistant restorer lines.
