Correlation And Path Coefficient Analysis For Certain Metric Traits In Okra (Abelmoschus Esculentus (L.) Monech) Using Line X Tester Analysis

The present investigation was conducted to find out the Correlation and Path coefficient effects in okra to identifying the desirable combiners. The experiment comprising 60 hybrids obtain by crossing using 19 parents (four lines viz., Arka Anamika, Arka Abhay, Parbhanikranthi, Varsha uphar and fifteen testers viz., IC-332453, IC-433640, IC-326893, IC-332454, IC-433672, IC-433670, IC-328942, IC-433690, IC-433673, IC-33102 , IC-433695, IC-331067, IC-433675, IC-433645 and IC-331217. The observation was recorded on plant height, days to 50% flowering, days to maturity, the node at which first flower appears, number of branches per plant, number of fruits per plant, length of the fruit, the diameter of the fruit, ten pods weight, fruit yield per plant, fruit yield per hectare, the node at which mosaic disease appears and days of first mosaic symptom appear were worked out through line x tester analysis. All the hybrids along with their parents were grown in a Randomized Block Design (RBD) with three replications at Student farm, college of Horticulture, Acharya N. G. Ranga Agricultural University, Rajendranagar, AndhraPradesh, India during Kharif-2009 and Spring Summer-2010. Results pertaining that, fruit yield per plant showed highly significant positive association with a number of branches per plant and number of fruits per plant at phenotypic and genotypic levels in F1s. The path coefficient analysis was done to determine the direct and indirect effects on fruit yield per plant viz., plant height, days to 50% flowering, days to maturity, the node at which first flower appears, number of branches per plant, number of fruits per plant, length of the fruit, the diameter of the fruit, ten pods weight, the node at which mosaic disease appears and days of first mosaic symptom appear.
