Abstract: One of the major limiting factor of okra is the incidence of okra yellow vein mosaic virus, it’s transmitted by white fly (Bemisia tabaci Gen.) is the most serious disease of okra affecting both yield and fruit quality. Infection of 100% plants in a field is very common and yield losses range from 50 to 94% depending on the stage of crop growth at which infection occurs. Since the disease cannot be controlled properly by chemical means, the only practical solution of this problem is to develop tolerant/resistant varieties or hybrids. The present investigation for the Screening of Okra [Abelmoschus esculentus (L.) Moench] Hybrids for Yellow vein Mosaic Virus was carried out at Allahabad region with 11 hybrids and 3 check varieties during kharif -2014 under randomized block design with three replications. The data was recorded for sixteen quantitative characters including YVMV incidence viz., days to 50% germination, plant height(cm), number of leaves/plant, number of branches/plant, inter nodal length(cm), days to first flower appears, days to emergence of 50% blooming, first pod (fruit) occurring node, length of fruit (cm), fruit girth (cm), fresh weight of fruit (g), number of seeds per fruit, number of fruits per plant, fruit yield per plant (g), fruit yield per hectare (t) and per cent incidence of YVMV, to obtain and estimate the best hybrid for YVMV resistance and yield (quantitative) attributes. Out of which only 3 hybrids (OKHYB-6, OKHYB-7 and OKHYB-13) were found to have highly disease resistant and highest yield per hectare was found in the hybrid OKHYB-15 (24.5 t/ha) followed by OKHYB-10 (23.1 t/ha) and hybrid OKHYB-12 produced the lowest yield (14.7 t/ha) followed by Arka Anamika (15.4 t/ha).
