The paper presents the results of studying the variability of the morphological traits of the generative shoot Matthiola caspica (Busch) Grossh. in Piedmont Dagestan. The material for the study was the life processes of M. caspica of three cenopopulations: Buynaksky (Talgi, 270), Suleiman-Stalsky (Kasumkent, 410 m) and Tabasaransky (Maraga, 520 m) areas. The greatest contribution to the differentiation of cenopopulations by individual components of dispersion in the traits “length inflorescence” (39.9%), “length vegetative features” (38.5%), “number flowers” (37.1%) and index trait “density inflorescences” (16.5%). The distinctions revealed as a result of the discriminates analysis make it possible to select diagnostic characters that introduce specific differences in M. caspica cenopopulations within the Piedmont floristic region. The total accuracy of the classification matrix for the three studied cenopopulations was 82.2%, where the “Maraga” cenopopulation (90.0%) is highly self-identical.
