Combining ability analysis for quantitative traits in aerobic rice (Oryza sativa L.)

Author(s): D Malathi and S Suresh
Abstract: The present investigation was carried out in aerobic rice (Oryza sativa 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 viz., ADT 36 x Nootripathu, ADT 43 x PMK 4 and ADT 47 x PMK 4 was found to have superior mean and sca 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.
