Abstract: A total of fifty four hybrids were developed using six male sterile lines and nine restorer lines to study the heterotic potential of the synthesized hybrids. The hybrids and parents were evaluated for thirteen characters which includes eight biometric and five quality traits viz., days to fifty per cent flowering, plant height, number of productive tillers/plant, earhead length, earhead girth, test weight, single head grain weight, single plant yield, crude protein, crude fiber, beta carotene, iron and zinc. Out of fifty four hybrids evaluated, mean performance and standard heterosis revealed that the hybrids viz., ICMA 92777 x RIL 68_, ICMA 92888 x RIL 81, ICMA 94222 x RIL 53, ICMA 94222 x RIL 81 and ICMA 02777 x RIL 53 were found to be promising for yield contributing and nutritional characters.
