Twenty F1 hybrids from three CMS lines and eight pollen parents were evaluated to study the heterosis for various yield and quality traits in rice (Oryza sativa L.). The findings suggested that the magnitude of heterosis differed from character to character and cross to cross. Majority of the hybrids recorded desirable heterosis for grain yield. Among the rice hybrids exhibiting high heterosis for grain yield IR-68897A x Pusa Sugandh-3 IR-58025A x HUR-JM-59221 and IR-58025A x Pusa Sugandh-5 were top performers. The hybrid IR-68897A x Pusa Sugandh-3 recorded highest yield per plant and was among the best three performers for traits days to 50% flowering days to maturity and number of effective tillers per plant. Thus IR-68897A x Pusa Sugandh-3 may be considered as the best heterotic combination for yield and yield traits. Among the three high yielding hybrids IR-58025A x Pusa Sugandh-5 was found to be relatively better performing for majority of the quality traits. Thus IR-58025A x Pusa Sugandh-5 may be considered as the best cross combination if both yield and quality traits are taken into consideration.
