Abstract:
Lysine and methionine contents were determined in proteins of 21 rice samples including 17 varieties grown in 11 provinces. Ranges of lysine and methionine contents on crude protein basis were 3.21-3.76% and 1.63-2.06% respectively. The lysine content was found to be negatively correlated with the protein content of rice, but no correlation was found in case of methionine when they were expressed on the basis of crude protein. The absolute amounts of lysine and methionine were positively correlated with protein contained in the samples. The importance of breeding rice variety with protein of high lysine content was discussed in relation to promoting the protein nutritive status in South China.
