褐稻虱是上海郊区水稻生产上的主要害虫之一。为了保证水稻高产稳产,急需鉴定、筛选、培育粳稻型水稻抗虫材料。目前报导的抗褐稻虱水稻品种多属籼稻型。如国际水稻研究所(IRRI)于1966～1978年,从世界各地收集的33000多个品种中鉴定出约300个抗虫品种,都是籼稻型。在国内,江苏省农科院植保所近年来筛选签定了近5000份材料,我们从1977～1980年,共筛选了6249份材料(其中粳稻4222份),未能找到抗褐稻虱的粳型品种(品系)材料。为了尽快获得抗虫种质资源,特别是粳稻型抗褐稻虱材料,我们于1979年参加了国际水稻研究
Brown planthopper is one of the major pests on rice production in the suburbs of Shanghai. In order to ensure high and stable yield of rice, it is urgent to identify, screen and cultivate japonica rice insect-resistant materials. At present, the rice varieties resistant to brown planthopper are mostly indica rice varieties. For example, from 1966 to 1978, the International Rice Research Institute (IRRI) identified about 300 insect-resistant varieties from more than 33,000 varieties collected worldwide, both of which are indica rice varieties. In China, the Institute of Plant Protection of Jiangsu Academy of Agricultural Sciences has screened and signed nearly 5,000 materials in recent years. From 1977 to 1980, we screened 6249 materials (of which 4,222 were japonica varieties), and failed to find japonica resistance to brown planthopper Type (strain) material. In order to get the insect-resistant germplasm resources as soon as possible, especially japonica-resistant brown planthopper, we participated in International Rice Research
