国内外经验证明,培育抗虫品种是控制褐稻虱发生为害的经济、安全、有效的措施。为此,我们自1979年以来,开展了水稻品种对褐稻虱的抗性鉴定工作。在抗性鉴定方法上,一直沿用国际水稻所的“苗期集团筛选法”。几年来实践证明、这种鉴定方法能可靠地将高抗和抗的品种筛选出来,但不少中 Domestic and foreign experience shows that cultivating insect-resistant varieties is an economical, safe and effective measure to control the occurrence of brown planthopper. To this end, we have carried out the identification of rice varieties against brown planthopper since 1979. In the resistance identification methods, has been using the International Rice “seedling group screening Act.” Practice has proved that over the years, this identification method can reliably high resistance and resistance of the selected species, but many
