Evaluation of Indian bean genotypes against insect pests

V Chouragade, A Shukla, A Sharma and AK Bijewar

An experiment was conducted during rabi 2015-16, in randomized block design with eight treatments (six genotypes namely 2013 DOLVAR-1, 2013 DOLVAR-2, 2013 DOLVAR-3, 2013 DOLVAR-4, 2014 DOLVAR-3 and 2014 DOLVAR-4 and two standard check varieties Swarna Utkarsh and PEP) and three replications. Lablab genotypes were evaluated against insect pests by recording their incidence in each weather week. Seasonal mean population level of each insect species on different genotypes was subjected to analysis of variance at 5% level and considered to describe the genotypic preference of insect-pests. Major insect-pests recorded on different genotypes included aphid (Aphis craccivora Koch), jassid (Empoasca fabae Harris), whitefly (Bemisia tabaci Gennadius) and pod borer (Helicoverpa armigera Hubner).
Lowest seasonal mean populations (16.11 and 17.22 insects / 10 cm twig) of Aphis craccivora were recorded on genotypes 2013 DOLVAR-4 and 2013 DOLVAR-3, respectively which may be further evaluated and used in breeding programmes for developing resistant lines
