The combining ability analysis was estimated from a Line × Tester crossing programme proposed by Kempthorne in 1957. Total 24 crosses were evaluated from 12 lines and 2 testers. Experiment was conducted at research field of Rama University, Kanpur during year 2019-20 with an aim to evaluate okra hybrids for yield and its attributing traits. Various morphological parameters viz., days to 50% flowering, plant height(cm), number of branches/plant, length of fruit per plant(cm), diameter of fruit (cm), number of seeds per fruit, number of fruits per plant and edible fruit yield per plant (g) were recorded. Analysis of variance revealed that parents and hybrids differed significantly for most of the traits under study. The gca and sca effects were significantly different for majority of the traits. Estimates of gca effect revealed that Parbhani Kranti, K.S-325 and Pusa Sawni are good general combiners for fruit yield, number of fruits per plant and no. of branches per plant etc. The estimation of sca effects reveled that the cross combition Prabhani kranti x A.B – 1, KS 325 x A. B 2, B. O 2 x A. B 2 and K.S-312 x A.B-2 etc. were observed most promising for fruit yield per plant, fruit length, number of fruit per plant and plant length etc. Thus the parents showing high gca can be utilised in hybridization programme for production of promising recombinants, while the crosses showing high sca for specific characters can be directly used for hybrid development.

Keywords: Line × Tester, gca, sca, analysis of variance and okra
