Thirty-three brinjal genotypes received from NBPGR, Hyderabad were screened for collar rot disease and their mean performances were also assessed for yield related parameters at SKLTSHU, Hyderabad during Kharif, 2019. These genotypes were laid in Randomized Block Design with two replications to study the diversity and were laid in Completely Randomized Design with three replications in polybags to identify the resistant germplasm lines. The fungus was isolated from diseased brinjal plants of farmer’s field, purified and maintained on PDA for further experimentation. Mass culture of the pathogen was prepared on sorghum grains and inoculated in polybags before transplanting. The analysis of variance showed highly significant differences among the genotypes for all the traits studied. The genotype IC-136182 was superior for yield characters i.e., yield per plant (2.39 kg plant-1) and marketable yield per plant (1.16 kg plant-1) and IC-136366 recorded highest plant height (104 cm). Out of all genotypes studied, only four genotypes viz., IC-111074, IC-089905, Bhagyamathi and Arka Kusumakar exhibited resistant response while, the remaining shown susceptible to highly susceptible disease reaction for collar rot disease.The resistant genotypes identified through screening and mean performance can be used further for development of collar rot resistant high yielding genotypes.
