Seventeen cultivars of okra (bhindi) were screened for resistance agaist Okra Yellow Vein Mosaic Virus (OYVMV) under field conditions. The vector of OYVMV is Bemisia tabaci Genn. On the basis of mean disease incidence percentage and susceptibility rating cultivars Mahyco Bhindi No.64, Marval No. 1003 and 1004 were found to be resistant to OYVMV infection. Besides, fairly high degree of tolerance was obtained in seven lines viz., Mahyco No. 55, JK 045, JK-7315, Sonal, Kirthi, Karina, Malay-27 and Arica Anamilui under field conditions, which showed disease incidence ranging from 1.92 to 55.63 per cent. The yields among the germplasm differed significantly. The lowest mean yield of 39.42 q/ha was obtained for Arka Anamika; whereas, the highest mean yield 112.38 q/ha was recorded in Mahyco B. No. 55.
