Abstract: By means of the analytical techniques of GLM-multivariate, coefficient of variation, principal component and UPGMA cluster, the phenotypic quantitative characters of inflorescence of Agropyron mongolicum Keng from 6 natural populations and 2 cultivars in the central and eastern areas of Inner Mongolia were analyzed. The results showed that there were some differences on the phenotypic characters within and among populations. Meanwhile, the degree of variation among 6 natural populations was greater than that between 2 cultivars, and the differentiation of populations had a close correlation with the ecological factors.
