Abstract. The article presents materials on the study of polymorphism of populations of elecampane (Inula hclcnium L.), rough comfrey (Symphytum aspcrum Lepech.) and Caucasian comfrey (S. caucasicum M. Bieb.) in ecotopes of various natural zones of the Kabardino-Balkarian Republic. The adaptively important traits of the studied species include elements of productivity of the above-ground mass – shoot height and number of leaves (I. hclcnium), number and width of leaves, stem diameter (S. aspcrum), shoot height and leaf width (S. caucasicum). Most of the remaining traits studied are weakly consistent with changes in others due to variability under the influence of external factors (environmental indicators) or are more stable and have taxonomic significance (genotypic indicators). The studied species consist of many ecotypes and have a wide ecological amplitude. When environmental conditions change, adaptive traits change relatively little and differ significantly between individuals of different ecotypes. For the purposes of breeding in the forage production of the Kabardino-Balkarian Republic, ecotypes with a high real and potential yield of green mass arc promising – floodplainmarsh I. hclcnium, foothill S. aspcrum and periodically wet loose S. caucasicum.
Keywords: ecotype, selection, feed production, polymorphism, ccotopc, adaptability, variability
