A total of 31 wheat varieties（lines） released in different years in Huanghuai Area were selected as materials so as to study the carotenoids content,lipoxygenase activity, and some other quality traits of wholemeal. Results showed that carotenoid content and other quality traits had highly significant differences among varieties. Carotenoids content was significantly positive correlated with watersoluble pentosan and yellowness. Carotenoids content was significantly negative correlated with peak viscosity, hold through, breakdown, final viscosity, unit weight,formation time, and was negative correlated with peak time, protein content and stability time. According to cluster analysis, carotenoid contents in 31 varieties were divided into three major groups： one group had common carotenoid content, which included 19 varieties such as Meng 0318; one group had relatively low carotenoid content, which included 10 varieties such as Luomai23; and the last group had relatively high carotenoid content, which included 2 varieties such as Huaimai22. The average carotenoid contents of the three groups were 1.93, 1.07 and 2.99 mg/kg respectively.
