This is a reference book which describes importance, use and basic information relevant to okra and its improvement. 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,...
