Abstract:

Okra genotypes were evaluated for their genetic variability, character associationships and genetic divergence among fifteen quantitative traits by adopting Randomized Block Design. Significant variation were observed for all the traits except incidence of YVMV at 30 DAS indicating the vast scope for selection. Among the genotypes, 2014\OKYVRES-5 and 2014\OKYVRES-11 (0.00 to 1.39%) was identified as most resistant line with low incidence of YVMV disease at all the stages of crop growth. The genotype, 2014\OKYVRES-1 recorded significantly moderate no. of fruits (11.20), fruit length (12.63 cm), fruit girth (5.81cm) and average fruit weight (8.53cm) with highest total yield (4.39 kg plot-1 and 54.20 qha-1). The genotype showed significant tolerance to YVMV upto 30 to 45 DAS of incidence. The genetical studies indicated that direct selection through traits like no. of fruits plant-1, days to 50% flowering, plant height, fruit length and YVMV incidence at 30, 75 and 90 DAS will be effective for improvement in okra especially to develop a genotype having resistance and/or tolerance to YVMV. Being most divergent Cluster I (2014\OKYVRES-11 and 2014\OKYVRES-1) and Cluster II (VRO-6), hence expected hybridization might result in highly heterotic hybrid and other segregants. Incidence of YVMV is contributing maximum towards divergence suggested that special attention should given to this character while designing crop improvement programme in okra.
