一九八一年,国际水稻研究所把该所选育的,从IR5到IR54各品种,统一在筛选室内或田间进行抗虫性鉴定.这些虫害名称包括黑尾叶蝉、电光叶蝉,褐飞虱三个生物型、白背飞虱、卷叶螟、稻筒螟、二化螟、三化螟和稻水蝇.鉴定结果是:除了IR22对上述所有虫都不抗外,其余品种至少都能抗其中一种.IR5、IR8和IR24都只能抗黑尾叶蝉,IR26和IR30可以抗褐飞虱的、Ⅲ生物型,还能中抗二化螟,而IR36又比IR26、IR30多抗褐飞虱Ⅱ型和中抗三化螟.表现中抗白背飞虱的只
In 1981, the International Rice Research Institute (IRRI) identified the varieties bred from the IR5 to IR54 for resistance to insects in a screening room or in the field, including black-leafhopper, electro-optic leafhopper, Three biotypes, Sogatella furcifera, leafroller, rice stem borer, rice stem borer, rice stem borer and rice waterfly.The identification results are: except that IR22 is not resistant to all the insects mentioned above, at least the other varieties can IR5, IR8 and IR24 can only resist the leafhopper, IR26 and IR30 can be resistant to BPH, Ⅲ biological type, but also in the resistance to Chilo suppressalis, IR36 than IR26, IR30 and more resistant to brown planthopper Ⅱ Type and the resistance of Borer borer performance in white-backed planthopper only
