Studies on combining ability in okra [Abelmoschus esculentus (L.) Moench]

A line x tester analysis in okra was carried out with six lines and three testers to estimate the combining ability and variance effects. The combining ability and variances indicated the preponderance of non-additive gene action for all the characters. Studies indicated the scope for heterosis breeding in crop improvement in okra. Lines Mohanoor local, TCR2056, Gobi local and testers Parbhani Kranti and Punjab Padmini were adjudged as the superior performer for seed yield per plant based on general combining ability effects. The hybrid Mohanoor local x Parbhani Kranti found to be superior when SCA effects were considered for many of the traits.
