Abstract
<p>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, there is a low yield of potatoes in the whole country, and the region for a long period of time. Harvest potatoes annually produced in Russia is much lower than the world's, and does not meet the genetic capabilities 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, selecting specifically for each class of nutrient media and the individual components of the environment, providing maximum parameters of plant growth and productivity in the future. During the studies the authors studied the effect of vitamin nutrient medium component of the recipe Murashige and Skoog medium, containing in its composition, thiamine, pyridoxine and niacin. These substances are involved in the co-enzymes and biochemical reactions mngih plants. The effect of vitamin complex on the performance of the above-ground parts of the plant (plant height and number of internodes), as well as indicators of root formation (number and length of roots) for plants regenerated total of four potato varieties: Adretta, Red Scarlett, Lubava and Kuznechanka. In the course of the study demonstrated a positive effect of vitamin component indicators of plant morphogenesis. For each class chosen his optimal ratio growth medium.</p><p> </p>
