title: Morphological and molecular genetic variations of oat genotypes grown in Kermanshah, Iran.
abstract: Morphological traits and molecular markers are two common methods for genetic variation studies. Molecular markers, morphological traits methods and relationship between the two were used to study genetic variation among 43 oat genotypes and varieties. For this purpose, an augmented design was conducted in three replicates at 2008-2009 cropping season in the experimental field of Campus of Agriculture and Natural Resources of Razi University, Kermanshah, Iran. Four wild oat accessions (Avena sterilis) were added to evaluated genotypes in molecular experiment. Results showed a significant variation among genotypes for all morphological traits and they were classified based on this variation in four groups by WARD cluster analysis. In molecular experiment, 28 inter simple sequence repeat (ISSR) primers amplified 206 polymorph bands. Based on Jaccard similarity matrix, similarity among genotypes was varied from 0.23 to 0.66 and cluster analysis classified genotypes in seven groups by complete linkage method. The correlation between ISSR marker and morphological traits classifications was not significant. ISSR showed to be a helpful marker for genotype identity and separation as it put wild accessions in a group.
