摘要
选用不同时期在黄淮地区推广的31个小麦品种(系)为材料,探讨其全麦粉类胡萝卜素含量、脂肪氧化酶活性等若干品质性状的品种间差异及类胡萝卜素含量与若干品质性状的相关性。结果表明,类胡萝卜素含量、脂肪氧化酶活性、总戊聚糖、水溶性和非水溶性戊聚糖含量、色差仪参数、RVA参数、近红外参数等品质性状的品种间差异均达到显著。类胡萝卜素含量与水溶性戊聚糖含量、黄度呈极显著正相关;与高峰黏度、低谷黏度、稀懈值、最终黏度、容重、形成时间呈极显著负相关;与峰值时间、蛋白质含量、稳定时间呈显著负相关。对供试品种(系)的类胡萝卜素含量进行了聚类分析,将孟0318等19个品种(系)聚为一类,将洛麦23等10个品种聚为一类,将淮麦22等2个品种聚为一类,3个类别的类胡萝卜素含量平均值分别为1.93、1.07和2.99 mg/kg。
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.
