Assessment of genetic variation in Agropyron intermedium accessions using cytogenetically and morphological traits

In this study, the genetic diversity was investigated among eleven accessions of Agropyron intermedium using both cytogenetical and morphological characteristics. Based on the results of cytogenetical experiments, the basic chromosome number was x=7 in all of the accessions, but their karyotypic formula (K. F.) was varied. Based on the results of analysis of variance the accessions were significantly different for all traits except for short arm (SA). The Cluster analysis based on cytogenetical data, classified all accessions into three distinct groups. Analysis of morphological data showed significant differences among all the traits, Comparison of means revealed that the 890-4 and 890-13 accessions produced the highest Dry Weight (DW). Cluster analysis based on morphological data classified the accessions into three separate groups.
