摘要

The use of crop varieties resistant or tolerant to insect pests stress is an imperative approach in non-chemical crop protection. In the presented studies, 16 genotypes of gram (Cicer arietinum L. were utilized for field assessment against gram pod borer (Helicoverpa armigera Hubner) (Lepidoptera: Noctuidae) to evaluate their genotypic differences. Results on identification of susceptible and tolerant genotypes observed significant differences among the genotypes tested for same traits under consideration. Based on the data for larval population, percentage pod damage and yield components, genotypes CM 2100/96 and CM-4068/97 were relatively resistant, while, lines No. 96051 and PBC-2000 susceptible against preference of the H. armigera in contrast to other genotypes. Oviposition activities of moth were also monitored to trace the eggs of pest on gram, weeds and crops growing around the experimental field. It is suggested that gram genotypes located as sources of tolerance for H. armigera deserve due attention for resistance breeding strategies, if gram has to remain a viable crop.
