Studies on genetic variability of nutritional traits among YVMV tolerant okra germplasm

Abstract

Thirty diverse okra genotypes were evaluated for 19 quality traits during the rainy season 2013. It was evident from the results that the genotypes, namely, DOV-11, DOV-66, DOV-24 and DOV-12 were recorded with no incidence of Bhendi Yellow Vein Mosaic Virus (BYVMV) after 30 days of sowing. No incidence of BYVMV disease was recorded in genotypes DOV-12 and DOV-66 even after 90 days of sowing. The popular variety, Pusa Sawani recorded 94% BYVMV incidence after 90 days of sowing. Mucilage content was found maximum in genotype Punjab Padamini (5.73%) and least in DOV-26 (3.35%). Genotypes Arka Abhay and USDO-2546 recorded maximum dietary fibre content (0.09 g/g). Based on path-coefficient analysis protein, dietary fibre, chlorophyll a and b and carotenoids content showed high positive direct effect on yield/ plant. Genotypes USDO-2546, Punjab Padmini and Arka Abhay were found suitable for utilizing in future breeding programme for developing variety with high nutritional quality. However, DOV-12 and DOV-66, which were having dark green pods were most desirable genotypes for BYVMV resistance and higher yield.
