Abstract

Field experiment was conducted at AICRP on Vegetable Crops of OUAT, Bhubaneswar during Kharif, 2018-19 to study the correlation of okra germplasm. Study on correlation between several characters shows that selection for fruit yield based on plant height, stem diameter, nodes plant-1, leaflet length, average fruit weight, fruit length, fruit girth, days to 1st flowering, days to 50% flowering, number of fruits plant-1, PDI at 30DAS, PDI at 45DAS, PDI at 60DAS, PDI at 75DAS. In present study genotypic correlation was observed to be higher than the corresponding phenotypic correlations for all the character combinations and therefore it shows that the suppression of phenotypic expression under the influence of environmental factors. Path coefficient analysis of total fruit yield contributing attributes estimated that like average fruit weight had the highest positive effects followed by number of fruits plant-1, days to 1st flowering, plant height, PDI for YVMV at 60 DAS, stem diameter, node at 1st flowering, nodes plant-1, which indicated that these traits have to give much importance in selection programme for yield improvement in  okra.
