Combining Ability Estimates of Various Morphological and Quality Traits of Okra

Abstract

Okra (Abelmoschus esculentus L. Moench) is one of important summer vegetable of Pakistan. In the present study GCA effects of parents and SCA effects of crosses were estimated by using line × tester analysis. Five lines i.e. Clean strawless, Sanura, Okra Malka, 0019221, Krishna and three testers Sabz pari, Perbhani selection, Ikra-03 were crossed to develop 15 F1 hybrids. The parents along with their hybrids were evaluated in RCBD in three replications in the field during 2019. The GCA and SCA mean squares for plant height, number of fruits, number of leaves, Stem diameter, Fruit diameter, Protein content, Fiber content, Ascorbic acid, Ash content, internodal distance and Pubesence were significant. Among lines Clean strawless, Okra malka and Sanura whereas among testers Sabz pari and Ikra-03 were proved to be good general combiners for most of the traits. These parents suggested to be used in future programs for fixing the desirable traits. Among crosses Clean strawless × Sabz pari, Sanura × Perbhani selection,Sanura × Sabz pari, were proved to be best specific combiners for most of the characters. Whereas Okra malka × Sabz pari, Sanura × Ikra-03, Krishna× Ikra-03, 0019221 × sabz pari had significant mid and better parent heterosis for most of the traits under study. So these cross combinations may be used in the development of hybrid okra or in the improvement of different quality traits of okra.
