Abstract:
Okra (<em>Abelmoschus esculentus</em> (L.) Moench), is an important vegetable grown throughout the tropical and subtropical regions of the world. One of the major limiting factors of okra is the incidence of Okra Yellow Vein Mosaic Virus, its vector being whitefly. Infection of 100% plants in a field is very common and yield losses range from 50 to 94 per cent, depending on the stage of crop growth at which infection occurs. A total of 50 okra genotypes were screened for reaction to Okra Yellow Vein Mosaic Virus in three replications in Randomized block design under unprotected condition during summer 2016. The results exhibited that four lines were highly resistant (IC43735, VRO103, IC45818and IC45980), nine lines were moderately resistant, 13 lines were tolerant, 20 lines were moderately susceptible and four lines were susceptible to disease reaction. The highest yield per plant was observed in IC45980 (317.53g/plant) followed by VROB178 (312.50g/plant) and HRB-55 (305.15g/plant).
