Abstract
The present investigation entitled “Genetic evaluation of local genotypes of okra (Abelmoschus esculentus ( L.) Moench.) under low hill conditions of H.P.” was conducted at Experimental Farm, Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (H.P.) during Rainy, 2018 to evaluate genotypes of Okra and to study variability, heritability, correlation and path analysis of different characters. The experiment was laid out in RCBD with three replications and 20 genotypes including two checks ‘P-8 and Palam Komal’ for studying the extent of genetic variability and performance of each genotype. The present investigated studies revealed a significant difference among genotypes for all the characters studied. Genotypes like LC-16-18, LC-1818, LC-11-18, LC-9-18 and LC-5-18 were significantly superior over other genotypes and both the respective checks for yield and few other horticultural important traits of vegetable types and can be recommended as such for direct cultivation after multilocational testing in the state. The GCV and PCV were high for traits like internodal length, fruit weight, number of seeds per fruit and fruit yield per plant. High heritability coupled with high genetic advance as percentage of mean was observed for plant height, first fruiting node, internodal length, fruit weight, fruit yield per plant, number of seeds per fruit, number of fruits per plant, number of locules per fruit, fruit length and fruit diameter which indicates their improvement through simple selection method. Correlation analysis revealed that traits like fruit weight, 100 seed weight, number of seeds per fruit, fruit length, fruit diameter and number of fruits per plant had significant positive correlation with fruit yield per plant at both phenotypic and genotypic level. Further, path coefficient analysis suggested that fruit diameter had the highest positive direct effect on fruit yield per plant followed by 100 seed weight, fruit weight, first fruiting node, fruit length, number of fruits per plant and internodal length. Therefore, main emphasis should be given on these characters, while making selection in okra genotypes.
