摘要： 应用二次通用旋转组合设计方法，研究了褐飞虱生物型Ⅱ和孟加拉型的不同组成比例对抗生物型Ⅱ品种IR36抗性的影响。结果表明，当孟加拉型密度比例占69.40%、生物型Ⅱ密度比例占30.04%~30.60%时会使IR36由抗虫变为感虫。

Abstract: The influence of various composing proportions of rice brown planthopper biotypeⅡ and biotype Bangladesh on resistance of rice varieties were studied by using the rotational composite design of quadratic regression. The result indicated that the resistance of IR36 will be changed to susceptible when the proportion of biotype Bangladesh was 69.40% and that of biotypeⅡ was from 30.04% to 30.60%.
