Abstract:
Twenty six genotypes of okra including indigenous and exotic lines were evaluated for fourteen yield and yield attributing traits during summer 2018 in randomized block design with three replications at Education and Research Farm, Department of Agricultural Botany, College of Agriculture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Ratnagiri, Maharashtra, India. The analysis of variance (ANOVA) revealed significant differences for all the fourteen traits under study suggesting the existence of required genetic variation in the breeding material. Higher PCV and GCV estimates were recorded by plant height, fruit length, fruit yield per plant, shoot and fruit borer incidence on fruits, number of fruits per plant and yellow vein mosaic virus percent disease incidence. Moderate PCV and GCV was registered by fruit weight, internodal length, fruit diameter, number of nodes at first flowering, days to initiation while days to 50% flowering, number of locules per fruit and number of ridges per fruit recorded low PCV and GCV. High to very high heritability (broad sense) was observed for all the traits except number of ridges per fruit, number of locules per fruit and individual fruit weight. These three traits registered moderate heritability. High Genetic Advancement as percent of mean was recorded by some of the traits except internodal length, fruit diameter, Number of nodes at first flowering, fruit weight, days to initiation, number of ridges per fruit, number of locules per fruit and days to 50% flowering. The presence of variability in the germplasm helps in progressing the elite genotypes to utilise in breeding programme.
