MODE OF INHERITANCE OF POD SPININESS IN OKRA (Abelmoschus esculentus (L.) Moench)

Adil Hassan Ahmed Abdelmageed


The mode of inheritance of spininess in okra was investigated. Two okra cultivars, namely ‘Khartoumia spiny’ and the Indian cultivar ‘Pusa Sawani’ were used in this study. The two parents were self pollinated for three successive generations to fix the character under study. Crosses were made between ‘Khartoumia spiny’ and ‘Pusa Sawani’, and reciprocal F1’s, F2’s and all possible backcrosses were derived from the initial crosses. No reciprocal differences were found between F1 and F2 generation for pod spininess. Segregation in the crosses between the local cultivar ‘Khartoumia spiny’ and the Indian cultivar ‘Pusa Sawani’ indicated that the presence of spines on pods was controlled by single gene, with incomplete dominance.
