Heterosis for Yield and Yield Components in OKRA (Abelmoschus Esculentus L.)

The present investigation was undertaken with the objective of identifying the high yielding parents and F1 hybrids through Line x Tester mating design to estimate the heterosis.The experiment was conducted by raising four lines and fifteen testers as parents and their 60 F1 hybrids during kharif 2009 and spring summer 2010.The heterosis recorded for fruit and its thirteen component characters.The F1 hybrids, Arka Anamika x IC-331217, Arka Abhay x IC-331217, Arka Anamika x IC-326893, Arka Anamika x IC-443670, Arka Abhay x IC-332454 and Arka Abhay x IC-433675 recorded high degree of standered heterosis for yield and its contributing characters.High estimates of heterosis obtain in hybrid combinations revealed considerable genetic divergence among the parental lines.
