ABSTRACT
The present investigation was undertaken to estimate the heterosis ten Genic Male Sterile (GMS) based hybrids, twenty five regular hybrids. The magnitude of heterosis over the commercial check hybrid was high in the desirable direction for all the 12 characters studied. The results revealed that the crosses IIHR-294 X JNDO-5, GMS-1 X Varsha Uphar and GMS-1 X Parbhani Kranti were potential heterotic cross combinations as they showed high standard heterosis in desired direction for marketable yield per plant in order of their merit. Among the top three best hybrids mentioned above, the hybrids GMS-1 X Varsha Uphar and GMS-1 X Parbhani Kranti are being GMS based hybrids have got great commercial significance of saving 70% of the time and labour required for hybrid seed production by effective utilization of Genic Male sterility of these lines compare to regular hybrids.
