明恢63是以IR30×圭630杂交,于1981年春育成的,是我国人工制恢研究中第一个取得突破的优良恢复系。其恢复力强、恢复谱广、配合力好、综合农艺性状优良、抗稻瘟病、制种产量高。它既是我国杂交水稻组合配组中应用最广、持续应用时间最长、效益最显著的恢复系,又是我国新恢复系选育中贡献最大的优良种质。1984~1996年以明恢63恢复系配制的杂交稻组合有18个,累计推广面积达6560万hm2。其中汕优63累计推广面积5267万hm2。以明恢63为主体亲本育成的一大批新恢复系配制的组合中,通过省级审定的达17个。文章根据近几年的推广实践、体会与有关统计数据,系统论述了该恢复系的选育过程、特征特性,及其利用价值。
Minghui 63 is a cross with IR30 × Kyu 630, which was bred in the spring of 1981 and is the first excellent restorer line in the study of artificial restoration in China. Its resilience, broad recovery spectrum, with good, comprehensive agronomic traits, resistance to blast, seed production. It is not only the most widely used and the most prolonged and the most effective recovery line in hybrid rice combination, but also the best germplasm which is the most valuable in the breeding of new restorer lines in China. From 1984 to 1996, Minghui 63 restorer line hybrid rice combinations formulated 18, the cumulative promotion of an area of 65600000 hm2. Among them, the total area of Shanyou 63 was 52.67 million hm2. In Minghui 63 as the main parent bred a large number of new recovery system prepared by the combination of provincial-level approval of up to 17. According to the popularization practices, experience and relevant statistical data in recent years, the article systematically discusses the breeding process, characteristics and characteristics of the restoration and its value of utilization.
