Abstract


Okra [Abelmoschus esculentus (L.) Moench] is a choicest vegetable crop of India. Hence, an experiment wasundertaken to determine the nature of association among different yield attributes and their direct and indirect contributiontowards yield by involving F2 segregating population of the bi-parental cross (IIHR-875 X IIHR-478) during kharif season2017-18 at ICAR-KVK, Hiriyur (Tq), Chitradurga (Dist.). The correlation study revealed that, the positive and significantcorrelation were observed for number of fruits per plant, average fruit weight, fruit diameter, fruit length, stem girth, numberof branches per plant and plant height with respect to total yield per plant. However, there existed a negative associationwith number of ridges per fruit and number of locules per fruit for total yield per plant. Path co-efficient analysis revealedthat number of fruits per plant fruit diameter, stem girth, fruit length, days to 50 per cent flowering and first fruit producingnode had positively high and very high direct effects, respectively on total yield per plant. Hence, these quantitative traitscould be considered for formulating selection indices in the improvement of okra.
