Abstract:
Twenty F1 hybrid were generated from twelve parents through line x tester mating design, these F1s along with 12 parents and 3 commercial checks were evaluated to study the magnitude of heterosis. significant heterosis was found over mid parent, better parent and standard checks for all the traits studied in desirable direction. Maximum desirable heterosis was observed in the cross IC-293590 X EC-305653 for internodal length and number of nodes on the main stem over mid parent (-16.43% and 7.54%), Better parent (-19.46% and 6.25%). The cross IC-293590 X EC-305741 exhibited maximum standard heterosis over the mid parent (12.50%) and over the better parent (11.24%) for days to 50% flowering. High estimate of heterosis obtained in hybrid combination releveled considerable genetic divergent among the parental line and also reveals good scope for commercial exploitation of heterosis in okra.
