Screening of different genotypes/ crosses of tomato (Lycopersicon esculentum) for resistance to bacterial wilt (Ralstonia solanacearum) under field condition

Abstract

The present investigation was conducted at Department of Plant Pathology, C-block, Bidhan Chandra Krishi Vishwavidyalaya, Kalyani (W.B.) during 2017-08. The experimental material comprised of twenty genotypes of tomato and the experiment was laid out in Randomized block design with three replications. Result on bacterial wilt showed that five genotypes found to be highly resistant, eight genotypes found to be resistant, one genotype found to be moderately susceptible, one genotype found to be susceptible and five genotypes were found to be highly susceptible in field condition against bacterial wilt.
