abstract
Studies on susceptibility of different genotypes of okra to leafhopper, Amrasca biguttula biguttula were undertaken at Research Field of Post Graduate Institute, Department of Agricultural Entomology, Mahatma Phule Krishi Vidyapeeth, Rahuri during Kharif 2016 and 2017. Twenty okra genotypes were screened against leafhopper. None of the genotypes was found completely free from the infestation of leafhopper, although they differed significantly in their degree of damage and pest number to harbour. The genotypes OK-7, OK-9 and Arka Anamika were categorized as resistant and recorded least population of the pest. The genotypes Narendra, IC-128889, GM-5, EC-133336, Arka Abhay, IC-43733 and IC-69242 were moderately resistant, genotypes IC-90168, VRO-22, IC-45805, IC-282229, IC-45800 and EC-169378 as moderately susceptible whereas the genotypes IC-282268, IC-282292, IC-282288 and IC-140906 showed maximum population and categorized as susceptible to leafhopper.
