采用日立L-8800氨基酸分析仪测定了4个中籼稻不育系、8个中籼稻恢复系及由此配制的10个杂交稻F1代糙米氨基酸含量。结果表明,杂交稻F1稻米各组合间氨基酸含量有一定差异,10个F1中,以明两优6号、绿敏S/4HZ021和绿敏S/凤恢35氨基酸总量和必需氨基酸含量最高,绿敏S/4HZ021赖氨酸含量最高,明两优6号亮氨酸含量最高;F1代氨基酸总量和必需氨基酸含量(色氨酸未测)均高于双亲含量;母本中以绿敏S为好,用此母本选配的杂交组合氨基酸总量和必需氨基酸含量相对较高,绿102S为母本的组合在所有组合中最低;父本对F1代氨基酸含量影响受母本所控制,需考虑配合力等因素。
Hitachi L-8800 amino acid analyzer was used to determine the amino acid content of brown rice in F1 hybrids of 4 indica CMS lines, 8 indica rice restorer lines and 10 hybrid rice cultivars. The results showed that the amino acid content of F1 hybrid rice was different. Among 10 F1 hybrids, the total amino acid content and essential amino acid content of Mingliangyou 6, Green Sensitive S / 4HZ021 and Green Sensitive S / Fenghui 35 were the highest, The content of lysine in the green sensitive S / 4HZ021 was the highest, and the content of leucine in Mingliangyou 6 was the highest. The total amount of amino acids and the content of essential amino acids in the F1 generation (tryptophan not detected) were higher than that of the parents. S was better. The total amino acid content and essential amino acid content of the hybrid combinations with this maternal parent were relatively high, and the combination of green 102S as the female parent was the lowest in all combinations. The effect of paternal parents on the amino acid content of F1 was controlled by the maternal , Need to consider factors such as co-operation.
