Twenty eight rice genotypes were selected for identification of fertility restoration for three CMS lines (Pusa 6A, IR79156A and IR68897A) with WA cytoplasm. On the basis of pollen fertility (%) and spikelet fertility (%), restoration of fertility was identified. Out of the 28 genotypes, 5 genotypes (Dantheshwari, Akshyadhan, IR36, URG-42 and URG-30) showed complete restoration for two CMS lines i.e. Pusa 6A and IR79156A, URG-1 showed complete sterility for three CMS lines (Pusa 6A, IR79156A and IR68897A) and Anjali showed complete sterility for two CMS lines (Pusa 6A and IR79156A). Vandana showed partial maintainer for three CMS lines (Pusa 6A, IR79156A and IR68897A) and 2 genotypes (URG 24 and N22) showed partial maintainer for two CMS lines (Pusa 6A and IR79156A). NDR-97 showed partial restorer for the CMS line IR79156A and 6 genotypes (Baranideep, URG-8, URG-3, URG-5, URG-22 and MTU-1010) showed partial restorer for the CMS line Pusa 6A.
