Evaluation of Some Green Gram Genotypes against Whitefly, Bemisia tabaci Gennadius and Leafhopper, Empoasca kerri Pruthi under Field Conditions

Studies were carried out on 51 genotypes of green gram, evaluated to identify the genotypic response against whitefly, leafhoppers and yellow mosaic virus infestation during kharif, 2010 at CCS Haryana Agricultural University, Hisar. Out of 51 genotypes, MH 732, MH 717, MH 719 and MH - 125 (Basanti) and MH 717 harboured minimum population of whitefly (2.68 /cage/plant), green leafhopper (0.45 /cage/plant), brown leafhopper (0.15 /cage/plant) and mixed (green and brown) leafhopper (0.69 /cage/plant), respectively, as compared to maximum whitefly population observed on genotype SM 9-117 (8.30 /cage/plant), green leafhopper on MH 809 (1.12 /cage/plant), brown leafhopper on MH 748 and MH 808 (0.41 /cage/plant) and mixed leafhopper counts recorded on SM 9-113 (1.49 /cage/plant). Genotype MH 742 affected least 2.80 per cent with the incidence of YMV as compared to maximum (56 per cent) incidence on SM 9-112. Highest grain yield (908 kg/ha) was obtained from the genotype MH 742 as compared to 355 kg/ha lowest observed from the genotype SM 9-112.
