摘　　要：我国籼型恢复系的选育经历了两个发展阶段：（１）测交筛选恢复系；（２）测交筛选和人工制恢等多途径选育恢复系。目前，早、中熟恢复系选育取得一定进展，而迟熟恢复系选育仍处于徘徊，这是由于所用亲缘相近，遗传基础相似所致，因而提出了采用亲缘渐渗，拓展恢复系的遗传基础，培育超高产组合的技术对策。The restorer lines breeding in indica hybrid rice have undergone two stages:screening the restorer lines by testcross,and screening the restorer lines by testcross or cross breeding.Breeding in early-and medium-maturing restorer lines has made some progress but that in late-maturing restorer lines has not made obvious progress due to close blood relation and narrow genetic foundation in indica hybrid rice.The technical countermeasure of super-high-yielding combination breeding have been put forward in this paper.
