    Histochemical studies on micro and megasporogenesis in the interspecific F1 hybrid of Abelmoschus Esculentus x A. Tetraphyllus
    (Kerala Agricultural University, 1992) Suresh Babu, K V; Dutta, O P
    In the interspecific hybrid between Abelmoschus csculentus and A. tetraphyllus the developmental stages of male gamete were abnormal. Pollen mother cells underwent normal meiosis and restitution division. The restitution division gave raise to fertile pollen grains. The developmental stages of female gamete were not complete. The study revealed the degeneration of megaspores of the linear tetrad and thus formation of empty ovules. The megaspore tetrads were low in nucleic acids and protein. The sterility of the interspecific hybrid is attributed to break down of entire megaspores.
