Abstract: The present investigation was carried out in aerobic rice (<em>Oryza sativa</em> L.) with five ‘lines’ and six ‘testers’ crossed in a Line x Tester design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids. The results concluded that the parents ADT 47, Chithiraikar, N 22 and Poongar were the best general combiners and the crosses involving them would result in the identification of superior segregants with favourable genes for yield in aerobic condition. The hybrids <em>viz</em>., ADT 36 x Nootripathu, ADT 43 x PMK 4 and ADT 47 x PMK 4 was found to have superior mean and <em>sca</em> effects for many of the traits. So these hybrids were identified as superior hybrids and can be effectively utilized for further breeding programme to release as a new variety.
