据国际稻水研究通讯1986. 12(3)G. L. Shres-tha,R. R. Adhiking报导,尼泊尔Parwanipur BPH虫群看来是一种新褐稻虱生物型。 他们于1984、1985年冬季在感虫品种TNI上繁殖当地BPH虫群,在温室对具有不同抗性基因的8个品种筛选鉴定生物型,三次重复,每重复反复筛选二次,采用水稻标准评价方法在单个秧苗上记录受害,其结果如下(表1,在尼泊尔Birganj): 具有Bph_I抗性基因的摩德哥和IR26(抗生物 According to the International Journal of Irrigation Research 1986. 12 (3) L. L. Shres-tha, R. R. Adhiking reports that the Parwanipur BPH fauna in Nepal appears to be a new brown planthopper biotype. In the winter of 1984 and 1985, they breed local BPH swarms on the susceptible TNI. Eight species with different resistance genes were screened and identified in the greenhouse for three replicates. The replicates were screened twice with rice standard Methods The damage was recorded on individual seedlings and the results are as follows (Table 1, Birganj, Nepal): Moda and IR26 with Bph-I resistance genes
