To study the heterosis using wild abortive(WA) CMS lines on yield, quality and drought related traits in rice, 56 experimental hybrids were produced using Three WA CMS lines (Pusa 6A, IR79156A and IR 68897A) and 31 male genotypes. The present study showed that superior performance for all characters was not expressed in a single hybrid combination. However, different cross combinations were found to be superior for various characters. The top two high yielding crosses estimated on the basis of significant standard heterosis over SH (Arize6444) and SV (NDR-97) are Pusa-6A x HUR-105 and Pusa-6A x Pantdhan-12. The hybrids Pusa-6A x IR-36 and Pusa6A x HUR-105 showed relatively significant desirable heterosis for the quality traits viz., hulling recovery, milling recovery, kernel length, kernel breadth, kernel length breadth ratio. The hybrids IR 79156A x Danteshwari and Pusa6A x NDR-359 exhibited significant standard heterosis in desired direction for quality aspects along with higher magnitude of standard heterosis for yield. The hybrids Pusa6A x NDR-359 and Pusa6A x Pantdhan-12 showed relatively higher significant desirable standard heterosis over SH (Arize-6444 Gold) for the drought traits viz., chlorophyll content (at 90 DAS) and proline content.
