摘　　要：130 wheat varieties are selected as materials to test the LOX activity, whiteness, yellowness, carotenoids content and RVA parameters, which are to be analyzed by variance analysis, correlation analysis, cluster analysis and classified according to the origins. The result shows there are highly significant variations in LOX activity from varieties; LOX activity is positively correlated with whiteness, and significantly and negatively correlated with yellowness. Cluster analysis applying longest distance method based on LOX activity clusters all the varieties or lines into three major groups. There are great differences between the averages of LOX activity from varieties. LOX activities are discussed in the application of nutritional quality improvement in wheat.选用130份小麦品种(系)为试验材料,测定其脂肪氧化酶(LOX)活性,全麦粉白度,黄度,类胡萝卜素含量和RVA参数,并进行相关,方差,聚类分析和根据来源地分类。结果表明,LOX活性品种间差异极显著;LOX活性与全麦粉白度呈显著正相关,与全麦粉黄度极显著负相关;采用最长距离法进行聚类分析共聚为三类;不同来源地小麦品种(系)间LOX平均活性差异性较大;讨论了LOX活性在小麦品质改良中的应用等问题。
