Estimation of genetic parameters in okra for quantitative traits

Abstract

Ten genetically diverse okra genotypes were taken for the present investigation. All possible single crosses excluding reciprocals were made among these parents and all the 10 parents and 45 F1 swere sown in a randomized block design with three replications. Observations recorded on quantitative traits showed considerable genetic variability. High heritability estimates were recorded for plant height, fruit width, fruit length, number of fruits per plant and weight of fruit per plant in both parents and F1 generation. Genetic advance and genetic gain varied from 0.13 to 79.62 and 3.03 to 37.14, respectively. On the basis of correlation studies, fruit width was negatively correlated with fruit length (- 0.792) and positively correlated with weight of fruits per plant (0.662). Fruit length was positively correlated with weight of fruit per plant (0.703). Fruit width, fruit length, number of fruit per plant and weight of fruits per plant are most desirable characters, which affect the yield and such characters should be taken into consideration while making selection for overall improvement.
