() is a two-row cultivated barley used as food and as a feed crop. Chloroplast genome is an excellent way to study the genetic structure and evolutionary process of natural population of plant species in recent years. In this study, the complete chloroplast genome of was sequenced and analyzed: the size of the chloroplast genome is 136,462 bp in length, including a large single copy region (LSC) of 80,597 bp, a small single copy region (SSC) of 12,701 bp, and a pair of inverted repeated regions (IR) of 21,582 bp; the chloroplast genome encodes 129 genes, including 83 protein-coding genes, 38 tRNA genes, and eight rRNA genes; the overall GC-content of the chloroplast genome was 38.32%, with the LSC, SSC, and IR regions being 36.31%, 32.33%, and 43.83%, respectively. Phylogenetic analysis based on 32 species with the maximum likelihood (ML) method indicated that was closely related to .
（）是一种用作食物和饲料作物的两行栽培大麦。叶绿体基因组是近年来研究植物物种自然种群遗传结构和进化过程的一种极佳方式。在本研究中，对（）的完整叶绿体基因组进行了测序和分析：叶绿体基因组长度为136,462 bp，包括一个80,597 bp的大单拷贝区域（LSC）、一个12,701 bp的小单拷贝区域（SSC）和一对21,582 bp的反向重复区域（IR）；（）叶绿体基因组编码129个基因，包括83个蛋白质编码基因、38个tRNA基因和8个rRNA基因；叶绿体基因组的总体GC含量为38.32%，LSC、SSC和IR区域的GC含量分别为36.31%、32.33%和43.83%。基于32个物种采用最大似然法（ML）进行的系统发育分析表明，（）与（）密切相关。
