| Abstract/Description: | Antixenosis or non-preference mechanism of resistance to brown planthopper, Nilaparvata lugens (Stål) collected from Mahbubnagar district of Telangana state was studied in the selected rice gene differential entries along with susceptible resistant checks. Three gene differentials viz., RP 2068-18-3-5, RP BIO 4918-230S and PTB-33 were resistant with a damage score of 2.35, 2.7 and 1.7, respectively. Four genotypes viz., MTU 1010, IR 66, IR 72 and Ndiang marie were moderately resistant with a damage score of 3.1-5.0. On the resistant gene differentials, the brown planthopper probed more number of times and excreted less amount of honeydew and sucked more xylem sap. The results indicate the non-preference mechanism of resistance in terms of feeding in the brown planthopper on resistant gene differentials. The identified resistant gene differentials can be used as donors in breeding programmes. |
