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 Five rice cultivars with different resistance genes were used to collect the data from the fields of Ninghua, Zhaoan, Jianyang, Pinghe, Huangshi and stone of Putian, Shangyong of Dehua and the counties of Chengguan, Zhouning and Wuping The results showed that TN1 was harmed more than the other 4 rice species. The survival rates of TNP on TN1 in different regions, Population number, honeydew excretion were more than the other four varieties, indicating that 8 counties 10 brown planthopper genus 1. Based on the biotype determination results, the paper proposed the layout and breeding direction of the varieties resistant to brown planthopper in Fujian
