摘要: 根据9个不育系、5个恢复系以及由此配制的45个不完全双列杂交组合氨基酸含量的测定结果,分析了不同组合氨基酸含量的差异及其与亲本的关系。结果表明不育系和恢复系的必需氨基酸平均含量为3.202%~4.889%,占氨基酸总量的31.796%~33.394%;而杂交组合的必需氨基酸平均含量为3.616%~4.858%,占氨基酸总量的32.176%~33.016%;必需氨基酸含量依次是亮氨酸>缬氨酸>异亮氨酸>苏氨酸、赖氨酸、苯丙氨酸>蛋氨酸。平均氨基酸总量和必需氨基酸含量都有一定的杂种优势,但各组合间差异明显。

Abstract: 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: leucine>valine>isoleucine>threonine, lysine and pheny lalanine>methionine. 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.
