dc.description.abstractAn experiment was carried out at University of Agricultural and Horticultural Sciences (UAHS), Navile, Shivamogga during the year 2017-18 to study the genetic diversity for yield and seed quality traits in okra. The experiment was laid out in a randomized completely block design with three replications including thirty five okra genotypes. Analysis of variance revealed that highly significant differences were observed among the genotypes for yield and seed quality traits indicating existence of genetic variability in the genotypes. The estimate of phenotypic coefficient of variation was higher that the genotypic coefficient of variation with narrow differences indicated most of the characters were less influenced by the environment which provides scope for improvement through simple selection. High heritability coupled with high genetic advance as per cent mean was observed for total chlorophyll content and number of branches per plant indicating predominance of additive gene action and amenability for phenotypic selection in early generations. Fruit yield per plant had significant positive correlation with plant height, number of branches, number of fruits per plant and fruit length. High positive direct effect was observed between fruit yield per plant with fruit weight, number of fruits per plant and fruit length which are important characters to be accounted for gaining improvement in yield. Based on Mahalanobis D2 analysis, 35 genotypes were grouped into three clusters and cluster I (26) consisted highest number of genotypes. Among the traits studied plant height (21.18 %), days to 50 per cent flowering (17.14 %), fruit weight (16.13 %) and number of branches (10.08 %) contributed maximum to the total genetic diversity. The present study identified three promising genotypes viz., UHSB-L9, UHSB-L26, OkraB-1, OkraB-2 and OkraB-6, for yield and OkraB-1, OkraB-3, OkraB-6, OkraB-7 for seed quality which can be utilized for further crop improvement programme.en_US
