Some differences among essential amino acids contents of nine sterile lines, five restorer lines and their hybridized combinations in indica rice were analyzed. Essential amino acids contents of sterile lines and restorer lines were 3 202%-4 889%, those were about 31 796%-33 394% of total amino acids, and essential amino acids contents of their hybrid were 3 616%-4 858%, those were about 32 176%-33 016% of total amino acids. The amount of essential amino acids were: leucinevalineisoleucinethreonine, lysine and pheny lalaninemethionine. Total amount of amino acids and essential amino acids in hybrids were higher than those in their parents, but the differences were existed among hybrid combinations.
