ダイズ属植物の子実タンパク質含量とそのアミノ酸組成の亜属間および種間差異について

抄録

Using 6 species belonging to 2 subgenera of Glycine, the experiment was carried out to clarify the interspecific differences in the content and amino acid composition of the seed protein. The highest value of seed protein content was found in G. soja. This fact shows the feasibility of breeding soybeans with higher protein content by the interspecific hybridization, G. max × G. soja. Although there are some intersubgeneric differences in the pattern of amino acid composition, it may be difiicult to place our hope on the wild species belonging to the genus Glycine for the breeding of soybeans with higher sulfur-containing amino acid content.
