Line x tester analysis in okra (Abelmoschus esculentus L. Moench). A rapid breeding approach towards hybrid development

      Аннотация: This is a reference book which describes importance, use and basic information relevant to application of line x tester analysis for hybrid development in okra. In reference to heterosis, data was collected for yield, quality and resistance to YVMV and utilized for obtaining best cross combination for these traits. The analysis revealed highly significant genetic variation for most of the yield and resistance traits. Recent research findings in okra improvement aspects have been incorporated in the book. The present research would be fruitful during formulating heterosis breeding strategies for okra improvement. Methodology, experimental findings and their relation with earlier researches has been elaborated in the book. Heterosis and combining ability analysis revealed to find out the best cross combination over better parent in okra. The maximum net return and B: C ratio was obtained due to heterosis among various heterotic combinations. Present book is basically written for Vegetable Science Scholar and persons interested in Okra breeding research.
