The brown planthopper, the whitebacked planthopper, and small planthopper are destructive insect pests in Asia. Two genes conferring resistance to insect pests, derived from GRH- and BPH-resistant rice cultivars have been transferred to both Japonica and Indica genetic backgrounds through marker-assisted selection. These pyramided lines (PYLs) carry both GRH- and BPH-resistance genes in a BPH-susceptible japonica cultivar, Taichung 65 and an Indica cultivar, IR24. In antibiosis testing, the rates of surviving insects and of females with swollen abdomens were lower on the PYLs than on Taichung 65.Virulence-associated QTLs against resistance gene BPH26, were analyzed using the F2 population derived from an avirulent and a virulent strains of BPH. The virulence-associated QTLs were detected on two independent linkage groups. This study constitutes a gateway for future genetic analyses of virulence in BPH.

褐飞虱、白背飞虱和小飞虱是亚洲的破坏性害虫。通过标记辅助选择，从抗GRH和bph水稻品种中获得的两个抗害虫基因已转移到粳稻和籼稻的遗传背景中。在一个bph敏感的粳稻品种台中65和一个籼稻品种IR24中，这些金字塔系（pyl）同时携带GRH-和bph抗性基因。在抗生素试验中，pyl的成虫率和雌性腹部肿胀率低于台中65。利用从一株BPH毒株和一株BPH毒株衍生的F2群体，分析了针对抗性基因BPH26的毒力相关qtl。在两个独立的连锁组上检测到毒力相关的qtl。本研究为未来BPH毒力的遗传分析奠定了基础。
