[Variability of the protein and amino acid content in the rice grain].

The amino acid composition of raw protein of ten regional varieties of rice harvested in 1972 and 1973 was investigated. The amino acid composition was measured in the Hd-1200e analyzer. Coefficients of variations in the content of protein and invididual amino acids were determined in relation to the rice variety. Consistent correlation between the lysine concentration in the protein and the protein content in the grain was established. The influence of climatic conditions on the protein accumulation in the rice grain was noted.
