Evaluation of resistance in rice genotypes against the brown plant hopper (Nilaparvata lugens Stal)

Abstract

Rice genotypes were evaluated for resistance to the Brown Plant Hopper (BPH), Nilaparvata lugens Stal in SVPUA & T Meerut, were evaluated for resistance in greenhouse screening tests. Over a period of two years (2017 and 2018), 17 rice cultivars were screened using the plant standard seed box screening technique. The results showed 6 rice varieties viz. REMRE-1, RPMRE-2, RPMRE-3, RPMRE-5, RIL-501 and PTB-33 were possessing high level of resistance to the BPH. 3 rice varieties viz., Vallabh Basmati-24, Pusa Sugandha-5, Taraori Basmati and Pusa Basmati-1 were moderately resistant. 4 rice varieties viz., Kasturi, Vallabh Basmati-23, Vallabh Basmati-22, Improved Pusa Basmati-1460 were moderately susceptible and 3 rice varieties viz., Pusa Basmati-6, Pusa Basmati-1121 and Pusa Basmati-1509 were susceptible, according to standard evaluation system (IRRI, 1992) Standard Seed Box Screening technique (SSST).
