摘要	Genetic differentiation in natural populations is driven by geographic distance and by ecological features within and between natural habitats. Among the cereal species, barley is the most strongly adapted to the Qinghai-Tibetan Plateau (QTP). The objective of this study was to search for correlations between the genetic structure of QTP barley landraces and variation for ecogeographical factors. A set of 230 six-rowed naked barley landraces adapted to a wide range of ecological conditions in the QTP were genotyped using the Diversity Array Technology (DArT) platform. On this basis, two distinct populations and four subpopulations were recognized, each associated with a definable geographical distribution. Population structure appeared to be best correlated with altitude at the population level, but temperature and rainfall contributed markedly to the structure of sub-populations. Nine of the 22 outlier loci were identified as being under positive selection and related to traits potentially important for local adaptation. Some correlations between the variation in certain ecogeographical factors and allele frequency at particular DArT loci were observed. The identification of DArT markers potentially associated with adaptation traits should encourage the exploitation of this unique germplasm as a source of genetic variation relevant for barley improvement.
