Abstract:

Studies were carried out under glass house conditions to study the evaluation of resistance in some rice genotypes against Brown plant hopper, Nilaparvata lugens. Among the rice genotypes tested against N. lugens (Stal), Ptb 33 (the resistant check) lowest mean damage rating (1.00), while genotypes, PTB 41 exhibited a damage score ranging from (1.00-1.67), when compared to T(N)1 (9.00).The genotypes viz., Co 43, ADT 36, Columbia, Swarna, SR 26B were moderately resistant with damage rating of (3.00-3.67) and the remaining genotypes were moderately susceptible or highly susceptible.


Keywords: Resistance, Rice, Brown planthopper, Nilaparvata lugens.
