The lines are divided into 4 large morphotypes. A dendrogram of similarity of lines of the collection according to the studied traits is proposed. The variability of traits in the collection as a whole and in individual lines has been established. A mass of 1000 seeds was selected as a high rank identification from quantitative characters. In second place is the oil content of the seeds. Other quantitative indicators can not give the reliability of the results. From the qualitative traits, a high degree of difference has the traits of coloring and the length of marginal flowers, teeth and bubbles on the sheet, the position of the head and the length of the top of the outer leaves of the wrapper. Morphological and genetic identity was confirmed by crossing, biometric observations and morphological measurements of a number of crosses, using the methods of hierarchical clustering and molecular analysis. Two microsatellite polymorphic loci, ORS 509 and ORS 4, have been identified, which can be used to identify our sample lines.
