Abstract

The aim of this study was to analyze the genetic variability of 22 oat genotypes, of which 20 genotypes were common oats and 2 were naked oats, using 7 SCoT primers. Out of 40 fragments that were totally amplified, 26 were polymorphic, with an average number of 3.71 polymorphic fragments per genotype. The average percentage of polymorphism was 65.67%. The value of the polymorphic information content (PIC) ranged from 0.305 (SCoT12) to 0.674 (SCoT8), with an average value of 0.506. Using hierarchical cluster analysis, a dendrogram was constructed. The genotypes of oats were divided into two main groups. Two naked oats (Avena nuda L.), Czech genotype Izak and Slovak genotype Hronec, grouped side by side in subcluster Ia. The used SCoT markers showed the ability to identify and differentiate genotypes of the common and naked oats.
