摘要： 为了解不同地区间大麦种质蛋白质含量特点，寻求拓宽亲本资源，采用近红外分析方法测定了287份不同地理来源大麦种质籽粒蛋白质含量，对其分布特征及地区间差异进行比较分析。结果表明：所测大麦籽粒蛋白质含量变幅为8.00%~20.10%，平均值为12.43%，集中分布在10.00%~14.00%之间，最小值(8.00%)来自云南，最大值(20.10%)来自青海。蛋白含量地区间差异显著，表现为河南最高，平均达到14.49%，内蒙古最低，平均为9.62%，按蛋白质含量从高到低顺序依次排列为河南、青海、新疆、江苏、湖北、云南、安徽、内蒙古。地区间大麦籽粒蛋白质含量的变化反映了当地大麦的用途。

Abstract: Grain protein content of 287 barley germplasms from different origins were analyzed by using near infrared method in this study to understand the property of protein content and extend parent resources. Distribution and differences of grain protein content among diverse origins were compared and the results showed, grain protein content of 287 barley accessions ranged from 8.00% to 20.10%, averaged 12.43%, and assembled around the scope between 10.00% and 14.00%. The minimum protein content of accessions, 8.00%, derived from Yunnan Province, while the maximum, 20.10%, from Qinghai. Significant divergence of protein content existed among origins with the highest value of 14.49% arisen in Henan Province and the lowest value of 9.62% in Inner Mongolia. The order of origins based on protein content from high to low was Henan, Qinghai, Xinjiang, Jiangsu, Hubei, Yunnan, Anhui and Inner Mongolia. Variation of barley grain content among different origins reflected its diverse uses.
