摘要
简要回顾了北方粳型杂交水稻恢复系的研究历史,综述了粳稻恢复系在品质、产量、抗性等方面的研究进展,对当前杂交粳稻恢复系育种存在的问题进行分析,并指出今后恢复系选育的目标及分子育种技术将起到的重要作用。
The development history of the restorer lines of japonica hybrid rice in northern China were reviewed.The research progresses of restorer lines of japonica hybrid rice in grain quality, grain yield and pest and disease resistances were summarized.The existing problems of breeding restorer lines of japonica hybrid rice in China were analyzed.The breeding objective for restorer lines in the future was pointed out and the molecular techniques would play an important rote in breeding of restorer lines of rice.
