In the populations of Taxus baccata of Foothills and Inside Mountain Dagestan, we have studied intra- and interpopulation variability of morphological characters of yew berry. The article has a contribution of interpopulation differences in the feature of "diameter of funnel" with the highest rates in Buynaksk population and dependency of the form of yew berry from this feature. According to the results of discriminant analysis, we have revealed a distinction in populations on this basis, although the classification matrix has not given 100% of the forecast for any of them. It is found, that the seeds of Khunzah population have relatively large dimensions and yew berry has more flattened shape compared to piedmont populations, while the differences in populations based on seeds are more pronounced than based on yew berry at low volatility of the characteristics of the first indicators. It is shown, that the characteristics of seeds and yew berry of Khunzakh population indicate the presence of certain genetic differences between populations inside mountain and foothills, and that the higher dissemination activity of first population is aimed at self-preservation, due to the less favorable conditions for the species. It is expected that the low variability of the average values for yew berries of cypress characteristics indicates the stability of the soil and climatic conditions of its habitats
