The okra leafhopper Amrasca biguttula biguttula (Ishida) has emerged as a major threat, triggering significant yield losses. To address this, we aimed to screened okra genotypes for resistance or susceptibility against Amrasca biguttula biguttula was conducted at Centre for Organic Agriculture Research and Training, Department of Agronomy, Dr. PDKV, Akola during Kharif 2022-23. The trial consisted of 20 genotypes replicated twice in Randomized Block Design. The studies on field screening of okra genotypes revealed that none of the genotypes were completely free from the leafhopper infestation, although they differ significantly in their percentage of damage and number of populations. Among these PDKV Pragati, Arka Anamika, Parbhani Kranti and Akola Bahar were found with least average population < 3.346 leafhoppers per 3 leaves per 5 plants and graded under resistant category. However, the maximum mean population > 4.654 leafhoppers per 3 leaves per 5 plants was observed on the genotypes Korchi × Phule and Vijayalaxmi were categorized as susceptible.

Study on screening of okra germplasm against leafhopper during 2022-23 concluded that PDKV Pragati, Arka Anamika, Parbhani Kranti and Akola Bahar were found to be resistant recording significantly less population of leafhopper. These genotypes are recognized as a source of resistance and could be used in breeding programme and development of IPM Strategies.
