Abstract: Interspecific variability of three species of the genus Nepeta L. (N. pamirica, N. pannonica and N. subsessilis) was studied with their introduction in the mountainous conditions of Dagestan on the basis of a complex of morphological features of generative shoot. The evaluation of the examined features revealed that along the length and mass of the shoot these species superior are widespread and most productive species N. grandiflora. Weight features of all three species are at a high level of variability. Most of the traits studied are in a positive correlation with each other. Reproductive effort positively correlates with the mass of shoot, but the foliage — not always. The results of the studies make it possible to evaluate the studied species as being resistant to the conditions of introduction, and recommend for cultivation in the mountainous zone of Dagestan.
