摘　　要：分析了来自全国不同地区和澳大利亚及加拿大的一些大麦基因型的β-葡聚糖含量,并在我国冬大麦区设置8个试验点,分析10个大麦品种在各点种植两年的β-葡聚糖含量。结果表明,我国西藏和新疆大麦的β-葡聚糖含量总体水平较高,特别是西藏具有高达8％以上的基因型,适合用于保健食品或药物的开发。我国冬麦区目前栽培的大麦品种的β-葡聚糖含量与澳大利亚及加拿大的啤用大麦类似,部分品种在杭州种植后β-葡聚糖含量明显降低,平均值显著低于原产地种子。10个大麦品种在8个试点种植,β-葡聚糖含量在品种间、地区间以及年度间均存在着显著差异。两年平均,秀麦3号和港啤1号分别为β-葡聚糖含量最高和最低的品种,泰安和杭州是β-葡聚糖含量最高和最低的试点。AMMI模型分析表明,品种与环境之间的互作效应两年试验均达极显著水平,且这种互作效应因品种而异,启示出特定地区合理选用品种在改变大麦β-葡聚糖含量上有积极意义。β-glucan is a polysaccharide compound closely related to the quality of barley used as malting, feed and food. Low β-glucan content is expected for brewing and feed barley, while high β-glucan content is desirable for food barley. In this study β-glucan content of barley genotypes collected from various areas of China and as well as from Canada and Australia were assayed. Meanwhile a multi-locations trial was conducted to determine β-glucan content of 10 barley content in each location for two successively planting years. The results showed that barley genotypes from Tibet and Xinjiang had higher β-glucan content and the genotypes with higher than 8% of β-glucan content were detected in Tibet barley accessions, being valuable for use in development of healthful food. Barley cultivars being planted now in winter-sowing areas of China had the basically same β-glucan content as those from Canada and Australia. Barley seeds produced in Hangzhou had lower β-glucan content, in comparison with seeds from the original areas. There were highly significant difference in β-glucan content among 10 barleys, among 8 locations and between years. On a average of two years, Xumei 3 and Kongpei 1 had highest and lowest β-glucan content, respectively, and Taian and Hangzhou produced the highest and lowest β-glucan content barley seeds, respectively. Analysis of AMMI model showed that interaction effect between cultivar and environment was highly significant in both experimental years, and was dependence on cultivar, suggesting that it is important to plant the suitable cultivars in a particular area in order to obtain barley seeds with reasonable β-glucan content.
