Field screening of rice germplasm for resistance against brown plant hopper, Nilaparvata lugens (STAL)

A total of 178 rice genotypes from various station and national trials were evaluated for resistance against brown planthopper (BPH) under natural infestation condition during kharif 2011 at CCS HAU, Rice Research Station, Kaul, Kaithal. The results revealed that only 5 genotypes viz ., CN 1724-9-4-5, MAUB-181, ACC-451 and IR 79584-38-2-1-9 were resistant, 28 were moderately resistant, 102 moderately susceptible and the rest were susceptible (43) to brown planthopper.
