(一)研究概况抗虫品种是水稻害虫综合防治的基础,而抗虫育种的前提是抗源。多年来国际水稻研究所已鉴定出具抗螟虫、高抗稻叶蝉、褐稻虱、白背飞虱、稻瘿蚊等抗源,并育成 IR36、IR64等一系列多抗高产品种。我国对水稻抗虫性的研究70年代已逐渐开展,但由于起步较晚,加上国内又未发现高抗褐稻虱等害虫的品种资源,故抗虫育种工作进展较慢。1980年起我们在中国农科院组织下与广西、湖南、浙江、福建等省的有关科研单位参加了“IRTP”(国际水稻试验计划)的有关试验。在1979—1985年中我们完成的主要研究内容有:
(A) Research Overview Insect-resistant varieties is the basis for integrated pest control, and insect-resistant breeding is the premise of anti-source. For many years, the International Rice Research Institute has identified resistance to stem borers, high resistance to rice leafhoppers, brown planthoppers, white-backed planthoppers, rice gall midge mosquitoes and other resistance sources, and bred a series of IR36, IR64 and other high-yielding varieties. Research on pest resistance in rice in our country was gradually carried out in the 1970s. However, because of the late start and the lack of species resources that are highly resistant to pests such as brown planthopper in China, progress in insect resistance breeding has been slow. Since 1980, under the organization of the Chinese Academy of Agricultural Sciences, we have participated in relevant experiments of “IRTP” (International Rice Experiment Program) with relevant scientific research units of Guangxi, Hunan, Zhejiang and Fujian provinces. In 1979-1985 we completed the main research content:
