In order to develop an effective analytical and monitoring method in breeding rice varieties with higher resistance stability to brown planthopper (BPH), Tai's method (1971) was employed to estimate the resistance stability of twelve rice varieties to different biotypes of BPH. It was shown that light intensity, seedling age, and nitrogen application rate had significant effects on the resistance performance and stability of rice varieties to different BPH biotypes. Among the varieties with resistance to BPH biotype II, the RHT, RP1976-18-6-4-2, and Ptb33 showed stable, IR56 showed unstable, while IR36 and ASD7 showed the most unstable resistance; whereas among the varieties susceptible to BPH biotype II, the TN1 showed stable, Guihuazhan, Foshanyouzhan and IR26 showed relatively stable, while Guojing No. 4 and Mudgo showed unstable susceptibility. For the rice varieties resistant to BPH biotype Bangladesh, the RHT, RP1976-18-64-2 and Ptb33 presented unstable, and IR56 presented very unstable resistance; whereas for the varieties susceptible to BPH biotype Bangladesh, the Guihuazhan, Foshanyouzhan and IR26 performed stable, TN1 and IR36 performed unstable, and Guojing No. 4, Mudgo and ASD7 performed the most unstable susceptibility.
为了开发一种有效的分析和监测方法，用于培育对褐飞虱具有更高抗性稳定性的水稻品种，采用了Tai（1971）的方法来评估12个水稻品种对不同褐飞虱生物型的抗性稳定性。结果表明，光照强度、秧龄和施氮量对水稻品种对不同褐飞虱生物型的抗性表现和稳定性有显著影响。在对褐飞虱生物型II具有抗性的品种中，RHT、RP1976 - 18 - 6 - 4 - 2和Ptb33表现出稳定的抗性，IR56表现出不稳定的抗性，而IR36和ASD7表现出最不稳定的抗性；而在对褐飞虱生物型II敏感的品种中，TN1表现出稳定的敏感性，桂华占、佛山油占和IR26表现出相对稳定的敏感性，而国粳4号和Mudgo表现出不稳定的敏感性。对于对孟加拉褐飞虱生物型具有抗性的水稻品种，RHT、RP1976 - 18 - 64 - 2和Ptb33表现出不稳定的抗性，IR56表现出非常不稳定的抗性；而对于对孟加拉褐飞虱生物型敏感的品种，桂华占、佛山油占和IR26表现出稳定的敏感性，TN1和IR36表现出不稳定的敏感性，国粳4号、Mudgo和ASD7表现出最不稳定的敏感性。
