水稻品种对害虫抗性的筛选方法是水稻抗虫育种和抗虫性研究的基础。关于水稻品种对褐飞虱抗性的筛选方法,国内外均已有报道(巫国瑞等,1976;1983;1984;吴荣宗等,1984;IRRI,1977)。至于对白背飞虱抗性的筛选方法,国外最近亦有报道(Khush,1982)。我们自1978年开始进行白背飞虱抗性的筛选和研究,1984年开始又承担了全国水稻育种攻关协作组常规大组关于白背飞虱抗性的鉴定工作,现将有关方法和结果简报如下
Screening methods of rice varieties for pest resistance are the basis for insect resistance breeding and insect resistance research in rice. Screening methods for resistance of rice varieties to BPH has been reported both at home and abroad (Wu Guorui et al., 1976; 1983; 1984; Wu Rongzong et al., 1984; IRRI, 1977). As for the screening method for whitebacked planthopper resistance, it has recently been reported abroad (Khush, 1982). Since 1978, we have carried out screening and research on whitebacked planthopper resistance. Since 1984, we have undertaken the identification of white-backed planthopper resistance in the conventional group of the National Rice Breeding and Counter Cooperation Group. Now, we are briefed on the methods and results as follows
