明恢63是用IR30与圭630杂交育成的。汕优63是珍汕97不育系与明恢63配组育成的杂交水稻新组合。它具有高产、优质、抗瘟和适应性广等优点,成为全国杂交水稻中主要的当家组合。1982～1985年参加全国、省、市三级区试,多居首位。平均亩产482.0公斤,比对照组合(汕优2号、6号等)平均亩增68.0公斤,增产16.15％。三年(1983～1985年)来在南方稻区各省推广近千万亩,1986年达3500万亩。1985年全国推广1000万亩估计增产稻谷6.5亿公斤,其社会经济效益将超过1.5亿元。根据栽培技术研究和大面积生产示范实践证明,汕优63仍有很大潜力,抓好良种良法,可达到更高的产量,取得更显著的经济效益。
Ming Hui 63 is IR30 and Kyu 630 hybrid breeding. Shanyou 63 is a new hybrid rice combination composed of Zhenshan 97 male sterile line and Minghui 63. It has the advantages of high yield, high quality, anti-blast and wide adaptability, and has become the main combination of the national hybrid rice. From 1982 to 1985 to participate in the national, provincial and municipal levels test, ranking first place. The average mu yield 482.0 kg, compared with the control combination (Shanyou 2, 6, etc.) an average increase of 68.0 kg mu, an increase of 16.15%. Three years (1983 ~ 1985) to promote nearly 10 million mu in the southern rice provinces, up to 35 million mu in 1986. In 1985, it was estimated that 1000 million mu of paddy will be boosted 650 million kg of paddy, and its social and economic benefits will exceed 150 million yuan. According to the cultivation technology research and demonstration of large-scale production and demonstration, Shanyou 63 still has great potential and good varieties of good law can achieve higher yields and achieve more significant economic benefits.
