摘　　要：为了解基因型、环境及互作效应对西藏春青稞β-葡聚糖和食用纤维含量的影响,选择西藏不同地区春青稞8个品种(品系),分别在四个地区种植,对其β-葡聚糖和食用纤维含量进行了分析。通过方差分析表明:不同春青稞品种(品系)的β-葡聚糖含量在四个地区间存在差异,而食用纤维含量没有差异;地区间的青稞品种食用纤维含量存在差异,β-葡聚糖含量则不存在差异;从基因型、环境以及基因型与环境互作对二者含量的影响分析得出:在本试验条件下青稞β-葡聚糖含量的变异主要来自供试品种和环境的互作效应作用,其次是品种间差异,环境作用相对较小;而对食用纤维含量的变异主要来自环境效应作用,其次是品种和环境的互作效应,而品种间的差异相对较小。用AMMI模型对β-葡聚糖与食用纤维基因型和环境互作的影响进行分析可以看出:990852在各区域的β-葡聚糖平均含量相对较高,PCA1值较小,对环境的反应比较稳定,是β-葡聚糖含量较理想的品种;品种990625、山青24和喜马拉雅19的食用纤维含量相对较低,但其PCA1值很小,即与环境的互作效应很小,是食用纤维含量较理想的品种。In order to understand the effect of genotype, environment and their interactive effects on content of β - glucans and dietary fiber content in Tibet highland barley. The content of β - glucan and dietary fiber from 8 Tibet spring highland barley varieties which were planted in four different Tibet areas were tested and analyzed. The resuits analyzed by variance analysis showed that there were differences of the content of β - glucan on spring highland barley varieties, but there ware no difference of the content of dietary fiber. There were differences of the content of dietary fiber in local highland barley varieties, but there was no difference of the content of β - glucan. The results of influence analysis from genotype, environment and their Interactive Effects on the two contents showed that the differences of the content of β - glucan from barley were major attributable to the interactive effects between cuhivars and environments, the difference amony varieties were the second reasons , and environment effect were relative low. The differences of content of dietary fiber were major attributable to environment effect, tested cuhivars and interactive effects of environment were the second reasons, and the differences between varieties were relatively low. Analysis of genotype and environment interactive effects on content of β - glucan and dietary fiber by AMMI model showed that average content of β - glucan in variety 990852 from different areas was relatively high, PCA1 value was less, and the effect of environment was stable. The variety 990852 was relatively ideal variety for the content of β - glucan. The content of dietary fiber in variety 990625, shanqing24 and ximalayal9 relatively low, but PCA1 value was very little, that is very little with the interactive effects on environment, so they are ideal varieties for the content of dietary fiber relatively.
