Evaluation of pigeonpea genotypes for their resistance against pod fly, Melanagromyza obtusa (Malloch) under natural conditions

Abstract

An experiment was conducted to screen thirty one genotypes of pigeonpea with three checks viz., PUSA 992, PA 291 & UPAS 120 for their resistance/tolerance to M. obtusa under natural infestation. None of the genotypes was found resistant, but marked differences were noticed among different genotypes. On the basis of larval population of M. obtusa and pod damage twelve genotypes were found to be least susceptible, while nine genotypes were moderately susceptible and ten genotypes were highly susceptible on a rating scale of 1-9. © 2018, Malhotra Publishing House.
