| 摘 要： | 通过对褐稻虱苗期抗性测定,杂交稻新组合抗优80对褐稻虱表现抗性,抗性级别为1.0级,对褐稻虱存活率、取食量、种群建立等有很强的抑制作用;田间系统调查,抗优80上的虫量仅为感性品种汕优63上的1/7～1/20。因此,在褐稻虱中等或偏重发生年,抗优80上的虫量达不到防治指标,不需进行防治。

| Abstract: | The resistance of "Kangyou 80" to brown planthopper (BPH), (Lilaparvata lugens") was studied. Experiment showed that "Kangyou 80" had obivously effect on feeding,surival.population built-up of BPH and the grade of resistance was 1. 0 in seedling stage. Population density on "Kangyou 80" were 1/7-1/20 as on susceptible variety in field. Thus, it is unnessary to control BPH on the new variety of "Kangyou 80" in the years of medium population densities. |
