国际水稻所(IRRI)为保证热带和亚热带以水稻为主食的国家的粮食供应,从事以早熟、抗病虫、优质育种,取得了一定成就,积累了较丰富经验。现在,亚洲地区国家和国际两个研究体系的研究投资正在迅速增长。在亚洲进行国际研究,所得利润,自从1966年到1977年间,每年估计为76-102％。仅早熟水稻改良品种IR36每年就能帮助农民增加15亿美元的收入。显然,IRRI因为育出一批生育期比传统高秆品种短的多的新 International Rice Institute (IRRI) has made some achievements in early maturing, pest-resistant and high-quality breeding in order to ensure the food supply for tropical and sub-tropical countries where rice is the staple food and has accumulated rich experience. Research investment in both national and international research systems in Asia is now rapidly growing. International research conducted in Asia and the profits made have been estimated at 76-102% per annum from 1966 to 1977. The IR36, a precocious rice modification alone, can help farmers increase their income by $ 1.5 billion annually. Obviously, IRRI gave birth to a number of new varieties with shorter growth periods than traditional tall varieties
