Screening of rice varieties for resistance against brown plant hopper, (Nilaparvata lugens Stal)
Rice germplasm collected from Deogarh, Sundargarh, Jharsuguda, Sambalpur and Jagatsinghpur districts of Orissa and Raigarh district of Chhatishgarh, India were screened for their resistance against rice brown plant hopper (BPH). Out of 337 varieties screened, six varieties of CRRI accession numbers 35006 (Banaspati), 35070 (Panidubi), 35155 (Dhoiya bankoi), 35181 (Salkathi), 35184 (Dhobanumberi) and 35228 (Jalakanthi) were found to be highly resistant with score 1. Hence, these varieties can be effectively used in the breeding programme to develop BPH resistant varieties.
