Abstract
The protein content of nonglutinous and glutinous upland rice grains of 45 varieties from the Ibaraki Agricultural Experiment Station (experiment I) and of 47 samples of 19 varieties purchased by the government (experiment II) was determined. There was no difference in protein content between the nonglutinous and glutinous types. However, the results showed that the upland rice grains were high in protein content. The average protein contents of the grains on dry weight basis from experiment I and II were 11.52 and 11.82%, respectively.
