ABSTRACT
Identification of parental lines is crucial for developing specific hybrids with more fertility restoration leads to higher yields. Conventionally, the process of screening for the trait of fertility restoration is by tedious test cross progeny evaluation. We screened total of 73 different ecology-specific Indian rice varieties for the presence offertility restorer genes, by earlier reported SSR markersRM10313 and RM6100tightly linked to Rf3 and Rf4, respectively. Among these genotypes, 53.42% carried Rf3Rf3/Rf4Rf4, 57.5% carried Rf3Rf3/rf4rf4 andremaining 69.8% carried Rf4Rf4/rf3rf3 allelic combinations. In this study observed that among 73 genotypes 39 lines were reported as high fertility restoring ability. So,these 39 lines are used for crossing programme to develop the high yielding rice hybrids suitable for aerobic cultivation.
Key words: Hybrid rice, Molecular markers, Fertility restoration, Rf3, Rf4markers.
