Correlation and path coefficient analysis for yield and its components in okra (Abelmoschus esculentus (L.) Moench)

Twenty-four entries okra (Abelmoschus esculentus (L.) Moench), were evaluated in randomized block design with three replications at the Experimental Farm, Vegetable Research Station, Rajendranagar, Hyderabad, Andhra Pradesh, India during summer 2013. Correlation and path coefficient analyses revealed that total number of fruits per plant and total yield per plant not only had positively significant association with marketable pod yield per plant, but also had positively high direct effect on marketable pod yield per plant and are regarded as the main determinants of marketable pod yield per plant and direct selection through these traits will be effective. The genotypic correlation coefficient of plant height, number of branches per plant, intermodal length, fruit length, fruit weight and number of marketable fruits per plant with marketable yield per plant was significantly positive, but their direct effect on marketable yield per plant was negative or negligible suggesting that the indirect casual factors are to be considered simultaneously for selection. Total number of fruits per plant and total yield per plant had strong influence on marketable pod yield per plant and are the main determiners of marketable pod yield per plant.
