A cross between Brimful from Nepal (a scented variety with high protein) and Nippon bare (a Japanese rice variety) was carried out in 1977 and F_2-F_5 plants were grown from 1978 to 1982. The present experiment was conducted for getting the informations on breeding of rice variety with high protein. The results obtained are summarized as follows : Grain protein content in F_2 and F_3 plants showed wide and continuous distributions. Mean of F_2 plants was located between P_1 (high protein parent) and P_2 (low protein parent) and slightly lower than the mid parent (Figs. 1, 2). The narrow sense heritability of protein content based on the variance and co-variance of F_2 and F_3 plants was O.588. As concerns protein content and agronomic characters, result of F_5 plants did not show significant correlation except one line (Table 8). These results indicated that it was possible to select promising lines having high protein property and desirable agronomic characters. As compared with F_3 and F_4 generations, F_5 was high in mean value of protein content and also decreased in the genetic variance of protein one (Tables 1, 2, 7). High protein property showed the tendency of being bred in true in F_5 generation. As for amino acid contents in F_4 and F_5, there were significant differences among the lines in three amino acids per dry weight basis, not per protein basis, and the lines were far better in the trait than Nippon bare (Tables 4, 9). Significant correlation was observed between protein content and lysine and threonine per dry weight in F_4 and F_5 plants (Tables 5, 10). The promising lines which have high protein property and also relatively good agronomic characters were selected based on thc measured results in F_5 plants (Table 11).
