Evaluation of Certain Mungbean [Vigna radiata (L.) Wilczek] Genotypes for Resistance Against Major Sucking Insect Pests

Department of Entomology and Agricultural Zoology, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi-221005 (U.P.) India

Abstract

A field experiment was conducted at Agricultural Research Farm of Banaras Hindu University, Varanasi to investigate the resistance of mungbean genotypes against major sucking insect pests during kharif 2015. Results revealed that the mungbean genotype VGG 10–008 (4.98 whitefly/split cage) showed minimum infestation of whitefly and genotype MH 921 (8.77 whitefly/split cage) maximum infestation. In the case of jassid, maximum infestation was recorded on genotype LGG 460 (6.31 jassid/split cage) and minimum jassid infestation was recorded on genotype DGG 6 (3.31 jassid/split cage). Genotype LGG 460 (2.93 thrips/10 flowers) showed maximum infestation of flower thrips and minimum in genotype DGG 6 (1.28 thrips/10 flowers). Genotype PM 10–18 (7.73 q/ha) produced maximum yield and genotype LGG 460 produced minimum yield (2.47 q/ha).

Genotype VGG 10–008 showed resistant and MH 921 showed susceptible reaction for whitefly.

Genotype LGG 460 showed susceptible and DGG 6 showed resistant reaction against Jassid and flower thrips.

Genotype PM 10–18 produced maximum yield and LGG 460 produced minimum yield.
