Induction of pollen plant of hybrid offspring from cultivated and wild rice and their genetic expression

With the studies during these years, more efficient medium and method for anther culture of hybrid offspring from cultivated and wild rice have been gotten. By observation of their agronomic characters and disease resisance of pollen plant, their H_(1) showed genetic diversity and their H_(2)-H_(4) were provided with relative genetic stability. After hybridization between wild rice with high disease resistance and high heritability and cultivated rice with high yield and other good agronomic characters according to the breeding aim, new quality germplasm could be promptly obtained by anther culture and then strictly selection.
