Abstract

Field experiments were carried out during kharif 2014 and 2015 at the Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, for screening 20 green gram genotypes along with a local check, HUM-12 for resistance/susceptibility to whitefly Bemisia tabaci (Gennadius). Weekly observations on the incidence/cage were made on the 35th Standard Meteorological Week (SMW). The results revealed peak in population during the 39th SMW, and the mean incidence was observed to range from 3.02 to 9.12/cage; maximum was in the genotype ML 5 followed by SM 48 and ML 1059; and the least was in PM-5 (3.02/cage). The genotypes PM-5 (7.72 q ha−1), IPM 306-1 (6.96 q ha−1) and HUM-16 6.58 q ha−1) gave the maximum yield, while IPM 306-6 followed by IPM 05-3-22 were with the lowest yield.
