The paper identifies the need to use the techniques of modern biotechnology in primary seed potatoes in the Russian Federation. At present time, the playback of potatoes does not meet current phytosanitary requirements, moreover, there is a low yield of potatoes in the whole country and the region for a long period of time. The potato yield that annually produced in Russia is much lower than the world's, and does not meet the genetic capabilities of used varieties. Modern methods of biotechnology have undeniable advantages and make it possible to carry out year-round operation for the production of elite planting material of potato. Effective implementation of such activities is provided by careful selection of plant cultivation conditions in vitro, selection of breeding gound and environmental components for each variety in order to provide the maximum parameters of plant growth and productivity. During research we examined the effect of vitamin component of breeding ground according to the formula of Murashige and Skoog, containing thiamine, pyridoxine, and niacin (the co-enzymes that involved in biochemical reactions of the plants). The effect of vitamin complex on the above-ground plant parts (plant height and number of internodes), as well as indicators of root formation (number and length of roots) was studied for regenerated plants of four potato varieties: Adretta, Red Scarlett, Lubava, and Kuznechanka. We proved a positive effect of vitamin component on plant morphogenesis. For each variety we determined the optimal ratio in nutriculture medium.
