Combining ability of yield and yield components in okra

摘要

Okra [Abelmoschus esculentus (L.) Moench.] is an important vegetabie crop being native of tropical Africa. One of the major problem in okra cultivation in India is lack of locational specific high yielding varieties. In often cross-pollinated crops like okra, improvement in the past was based on selection in locally adapted populations. During recent past, exploitation of hybrid vigour and selection of parents on the basis of combining ability effects have opened a new line of approach in crop improvement. Application of biometrical techniques; the line x tester analysis appeared to be the best and vastly useful breeding tool, which gives generalized picture of genetics of the characters under study. Studies on combining ability help identify the best parents and provide sufficient genetic information on the inheritance of a character. Hence, the present investigation was undertaken to study the gene action in different quantitative traits and to study the combining ability for yield and its components in okra.
