摘要： 利用3对引物对47份品系进行Wx基因分子检测,其中3份白粒小麦为野生型材料,22份蓝粒小麦和22份紫粒小麦为Wx基因全突变型材料,即全糯小麦。对其部分氨基酸含量进行多重比较,结果表明,总体上蓝粒糯小麦氨基酸含量高于紫粒糯小麦,紫粒糯小麦高于白粒小麦;3种类型小麦精氨酸、半胱氨酸、赖氨酸、蛋氨酸、苏氨酸、缬氨酸含量差异极显著;异亮氨酸、色氨酸含量差异达显著水平。

Abstract: Three primer pairs of Wx gene were used in molecular detection from forty-seven wheat strains. Three white wheats were wild type material,twenty-two Blue grain and twenty-two purple grain of wheats were Wx gene mutation type materials,named the full waxy wheats. Multiple comparative analysis on part of the amino acid content. The results showed that amino acid content of the blue waxy wheats was higher than the purple waxy wheats, the purple waxy wheats was higher than white wheats; Arg,Cys,Lys,Met,Thr,Val content of the three types of wheat were extremely significant different,Ile,Trp content were significantly different.

Key words: Blue gain wheat, Purple gain wheat, Wx gene, Amino acid
