Screening of okra genotypes against yellow vein mosaic virus disease (OYVMV) under Field conditions in Allahabad

Abstract

The present study was conducted at central research farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad during Rabi season 2017. The experiment was conducted during March, to June, 2017 at Field of central field of SHUATS, Allahabad. There were 8 okra genotypes with diverse morphological characters collected from IIVR, Varanasi. The experiment consisted of 8 treatments and 3 replications in randomized block design. Based on disease scale, the data presented of screening of 8 different genotypes on okra against YVMV showed completely free/immune in (VRO-5) to Yellow vein mosaic virus incidence with 6.6 % disease and yield 40.23 q/ha, whereas genotypes (IC117216, IC140934 and Parbhani Kranti (check) were Moderate resistant while two genotypes (IC433695, and IC140906) were Tolerant against YVMV, and genotype (VRO-4) was Susceptible. The highest Susceptibility reach as was observed in IIVR-10, yield 53.12 q/ha.
