In this paper, possibility of screening with the DBC method for high lysine content in the materials consisting of 1271 Japanese local rice varieties, 9 lines of ecotypes and 9 species (12 lines) of wild rice were studied. The results showed good correlation between DBC and lysine and protein contents of the materials used in the present experiment. For the samples employed, the correlation coefficient between the DBC, the protein level of 102 varieties and lines of Japanese local rice, ecotype and wild rice was 0.893 and the lysine level of 31 Japanese local varieties, 0.885. Negative correlation coefficient between the protein and the lysine content per 100g protein was obtained as shown in Fig.3 (r=-0.938). From the result shown in Fig.3, significantly deviate plots toward positive side from the regression line are also assumed as high lysine varieties or lines.
