In the conditions of increasing of foreign varie-ties expansion with a steady downward trend in the share of domestic market of Russian seed po-tato there is an urgent need to overcome the de-pendence of producers from the import of seed material. The aim of the research was to define the requirements to the parameters of the main economically valuable traits to improve the com-petitiveness of the potato varieties of different tar-get use. Based on the analysis of efficiency of use of the assortment of potatoes, listed in the state register of the Russian Federation for 2015 re-vealed that out of 409 potato varieties really in the production were recorded only 214 or 50.3 %. Moreover, only 10 potato varieties amounted to 66.4 % from the total certified seed potato used on for ware potato production. Over the last 10 years the share of domestic varieties in the total volume of seed potato decreased by 29.6 %, and foreign varieties increased substantially by 26.0 %. Nega-tive processes were particularly apparent in the state resource potential and technological disci-pline of production of certified seed material of domestic potato varieties. Meeting the increased requirements of the consumer and table qualities of potato varieties and the structure of the target use are main directions of development of breed-ing programs for the near and long term. This will allow more efficient use of varietal resources by producers and provide of production and trade networks to meet distinct demands of consumers.
