✦ Synopsis

Three breeding lines (F8) of rice, derived from cross between Brimful X Koshihikari were tested for protein, amino acid, growth test with rats and yield parameters in field trials . The breeding lines had higher protein and amino acid concentrations than the leading Japanese cultivar Koshihikari, which was grown as a control . Grain yield in the breeding lines was lower than that of Koshihikari . (4 .5 t/ha) . The grain-protein yield of the breeding lines was higher (500 kg/ha) than that of Koshihikari (440 kg/ha) . The average gain in weight of rats fed brown and milled rices of the breeding line was 19 and 21 g, respectively : in control rats fed Koshihikari average gain was -1 and 8 g . These results showed that the breeding lines of rice can be developed which possess higher food value than the available varieties .
