Screening of mungbean (Vigna radiata) genotypes against major insects

An experiment was conducted at Banaras Hindu University, Varanasi, Uttar Pradesh during July to October 2012 for screening of 30 genotypes of mungbean [Vigna radiata (L.) Wilezek] against white fly (Bemisia tabaci), jassid (Empoasca kerri), flower thrips (Caliothrips indicus) and pod borer (Maruca vitrata). The minimum population of white fly was recorded on genotype TMB-36, followed by RMG-1004 and maximum in BM-2003-2 and HUM-12. The minimum population of jassid was recorded on KM-2293, followed by TMB-36 and Pusa-1271, while maximum in BM-4, followed by ML-1628 and BM-2003-2. In case of thrips, minimum infestation was found in ML-1628, followed by Pusa-1171, ML1464 and maximum in BPMR-145, followed by HUM-12 and Pusa-0672. According to pod damage, minimum damage was recorded in RVSm-11-9, followed by IPM-306-6, IPM 2K-15-4, MH-805, BM-4, DGGS-4 and BM-2002-2, and maximum in Pusa-1171, followed by HUM-12, BM-2003-2, Unnati, KM-2293 and ML-1628. Based on yield obtained at the time of harvesting, highest yield was recorded in AKM-4, followed by KM-2293, AKM-09-2, IPM-3066 and ML-1628. These genotypes were found resistant/tolerant against infestation of major insect pests of mungbean. The lowest yield was recorded with AKM-8802, followed NDMR-10-35, BM-4, ML-1464 and IPM 2K-15-4.
