Screening of certain green gram varieties/genotypes against Callosobruchus chinensis under laboratory conditions

Abstract

The susceptibility of 20 green gram genotypes/varieties i.e., PM-5, IPM 2K 14-9, HUM 1, ML 1257, Pusa 672, IPM 306-6, SM 48, IPM 05-3-22, Pusa Bold 2, IPM-9901-10, HUM 16, IPM 306-1, PM 4, ML 5, ML 1256, ML 1059, SML 191, ML 515, PDM 288 and HUM 12 to pulse beetle, Callosobruchus chinensis was studied under laboratory conditions. None of tahe genotype/variety was found immune to pest infestation and showed different magnitude of weight loss. The minimum infestation, minimum weight loss and minimum total adult emergence was recorded in genotypes PM-5 and IPM 306-1 and genotypes IPM 306-6 followed by IPM 05-3-22 showed maximum susceptibility in terms of infestation, weight loss and total adult emergence. © 2019 Malhotra Publishing House.
