Investigation was carried out for exploiting maximum hybrid vigour by combining earliness and yield potential in a single plant. The evaluation was based on the per se performance, sca and the standard heterosis. The hybrids AD 95134 x TRY 2 and BTCE 23/99 x ADT 43 were found suitable for simultaneous improvement of earliness and yield potential through heterosis breeding as these hybrids had desirable per se performance for grain yield per plant and biological yield per plant and earliness.
