【摘要】 采用具有不同抗性基因的 5个水稻鉴别品种 ,把从宁化、诏安、建阳、平和、莆田县黄石和笏石、德化县上涌和城关、周宁、武平等县田间采集的褐稻虱分别接在 5个鉴别稻种上进行福建省不同地区褐稻虱生物型的测定 ,结果表明 ,TN1受害比其他 4个稻种严重 ;不同地区褐稻虱在 TN1上的生存率、群体数量、蜜露排泄量均多于其他 4个品种 ,表明 8个县 10个点褐稻虱属生物型 1。文章根据生物型测定结果 ,提出福建省抗褐稻虱品种的布局和选育方向更多还原

【Abstract】 Five rice varieties with different resistant genes were used to study the biotypes of brown planthopper (BPH) collected from different regions of Fujian,such as Ninghua,Zhaoan,Jianyang,Pinghe,Putian,Dehua,Zhouning and Wuping in recent years.The results showed that the variety of TN 1 was infected most seriously.The survival rate,population amount of BPH and amount of honey dew excreted by BPH in TN 1 were higher than those of other four varieties.It was suggested that the BPH collected from ten localities in Fujian belong to the Biotype 1.Breeding strategy and selective direction of rice resistance to BPH were also discussed.更多还原
