Abstract

To make the rice cultivar 'Kozo-no-sumika' with a beautiful figure at the flowering time late ripened, it hybridized with ultra early ripened rice plant. The form and the genetic nature were investigated about the posterity of the crossbreed. As a result, being ruled by single inferiority and each dominant gene became clear from the morphological characteristic investigation as for the presence of the plant length and the awns. The length of glumes was thought for the possibility of rule by a single recessive gene to exist. The purple coloring matter synthesis's in the leaf being ruled by an independent two dominant supplementation gene became clear. It was suggested to show the incomplete dominance about ear emergence by a single gene. In the strain selection, it was suggested that the selection be able surely to be advanced. The difference between genotypes of the regenerated plant has grown in the anther culture. The possibility of succeeding the genotype and depending on the selection of the kind of the medium was suggested this time though the reproduction individual of F1 was not obtained.
