从陕西关中东部地区９个粮站的贮仓中抽取小麦商品粮样本１６个，测定其品质指标，并分析品质性状之间的相关性和小麦品质的地域差异及年际差异。结果认为：抽样地区北部低山丘陵区（海拔５５０～８００ｍ）小麦商品粮品质优于黄土台塬区（海拔４００～５５０ｍ）；该地区１９９５年入库小麦明显优于１９９６年入库小麦；小麦籽粒硬度、蛋白质含量和湿面筋含量能够较好地反映小麦商品粮的综合品质。
Sixteen wheat grain samples were taken from storage silos in nine grain stations in the eastern part of Guanzhong of Shaanxi Province. The quality indexes were determined and the correlations between the quality traits and the geographical differences and the interannual differences of wheat quality were analyzed. The results showed that the grain quality of wheat in the northern hilly region (550 ~ 800m above sea level) in northern sampling area was better than that of the Loess Plateau (elevation 400 ~ 550m); the wheat in storage in 1995 was obviously better than the wheat in 1996; Hardness, protein content and wet gluten content can better reflect the overall quality of wheat commodity grain.
