中文摘要:

为了解二棱皮大麦品种籽粒蛋白质含量的差异性与稳定性，以来源不同的334份二棱皮大麦品种（系）为材料，测定了6个环境下成熟籽粒的蛋白质含量。结果表明，二棱皮大麦籽粒蛋白质含量在品种（系）间、试点间及试点与品种（系）互作间均存在显著差异。依据10级分类分布频次法则，籽粒蛋白含量均主要分布在3~8级，趋于正态分布。通过计算籽粒蛋白质含量BILPs值及AMMI模型分析D_i值，筛选到稳定性好的高蛋白质品种（系）浙大96-6和华大麦8，稳定性好中等蛋白质品种(系)川52209和Nasonijo，以及稳定性好的低蛋白质品种（系）区146V025W和9919(中国新疆)。

英文摘要:

In order to understand the variability and stability of grain protein content in two-rowed hulled barley, 334 varieties(lines) from different sources were used as materials to determine the grain protein content under six environments. The results showed that there were significant differences in grain protein content among varieties(lines), environments, and the interaction between trial sites and varieties(lines). According to the 10-class frequency distribution rule, the protein content of grains in each environment was mainly distributed in grades 3-8, which tended to be normally distributed. By calculating the BILPs value of grain protein content and analyzing the D_i value of AMMI model, two stability varieties(lines) with high protein content were selected: Zhejiang 96-6, and Huadamai 8; two stability varieties(lines) with medium protein content were selected:Chuan 52209 and Nasonijo; and two stability varieties(lines) with low protein content were selected: Qu 146V025W and 9919(Xinjiang, China).
