Breeding of a restorer line for the male-sterile cytoplasm [ms-CW] of wild rice (W 1 ; Oryza rufipogon Griff.), identified by KATSUO and MIZUSHIMA (1958), was demon-strated by transferring the restoring gene(s) of W 1 to a cultivar through anther culture. Anthers of the F<SUB>1</SUB> hybrid between W I (=) and O. sativa L. cv. Somewake (=) were cultured and two regenerated plants with high pollen stainability were obtained. Of these two plants, one was sterile in seed set, but the other (A<SUB>1</SUB>) was fertile and its selfed progenies (A<SUB>2</SUB>) also showed a high seed fertility. In a test cross of one of A 2 plants (=) with a cytoplasmic male-sterile strain carrying the cytoplasm of W<SUB>1</SUB> and the nucleus of cv. Reimei, the resulting F<SUB>1</SUB> gave a high seed fertility, demonstrating that the regenerated plant (A1) possessed restorer gene(s). The F<SUB>2</SUB> and BIFI progenies of W<SUB>1</SUB> (=)/Somewake in the conventional crossing showed a wide variation in pollen stainability and seed fertility, that might be due to not only cytoplasmic but also genic hybrid sterility. These results suggest that anther culture is effectively utilized for breeding restorer lines from remote hybrids, especially when they suffer from hybrid sterility.
