摘　　要：[目的]本文旨在研究小麦类胡萝卜素含量与各品质性状间的关系及其在小麦品质改良中的应用,为小麦营养品质的改良和高、低类胡萝卜素含量种质资源筛选提供参考。[方法]以250个小麦品种(系)为试材,对其全麦粉类胡萝卜素含量、脂肪氧化酶(LOX)活性、白度和黄度等品质性状进行了方差分析、相关分析和聚类分析;对不同来源地品种的类胡萝卜素含量进行比较。[结果]250个小麦品种(系)籽粒全麦粉类胡萝卜素含量、LOX活性、白度和黄度的品种间差异均达到差异极显著水平。类胡萝卜素含量与全麦粉黄度呈极显著正相关,与LOX活性、全麦粉白度呈极显著负相关。北方地区小麦品种的类胡萝卜素含量平均值高于南方地区。[结论]来源于不同生态区域的小麦品种籽粒类胡萝卜素含量及若干品质性状存在显著差异;全麦粉类胡萝卜素含量与白度等性状相关性显著。[ Objectives ] In order to provide the reference of improving the nutritional quality and screening resources of wheat varieties with high and low carotenoid content, this article discussed the relation of carotenoid content with some other quality traits, and also discussed its application to quality improvement in wheat. [ Methods]250 wheat varieties（ lines）were selected as materials to test the carotenoid content,lipoxygenase activity, whiteness, yellowness and some other quality traits of whole-mill in wheat. The variance, correlation and cluster analysis were used for the traits above. The regional differences were compared with the carotenoid contents of wheat varieties from different originated areas. [ Results ] The results showed the variance displayed highly significant difference in lipoxygenase activity, carotenoid content, whiteness and yellowness among varieties. The carotenoid content was highly significant and positively correlated with yellowness, and negatively correlated with lipoxygenase activity and whiteness in high significance. The average of carotenoid content of wheat varieties in northern region was higher than that of southern region. [ Conclusions] There were significant differences in carotenoid contents and some other quality traits of wheat varieties in different ecological regions. The carotenoid content was significantly correlated with whiteness and other traits.
