One of the main methods of expansion of garden crops assortment is the introduction. For the Tambov Region the cornelian cherry is unconventional garden culture. The most significant economic and valuable trait of introduced plants is productivity. That is why the evaluation of potential productivity and features of interaction "genotype � environment" is the most interesting direction of research when the crops and varieties are transferred in the new environmental conditions. A main purpose of this work is the evaluation of the morphological components of productivity of introduced cornelian cherry varieties under the changing environmental conditions of the Tambov Region. 10 introduced cornelian cherry varieties on the base of a cornelian cherry collection of the All-Russian Research Institute of Horticulture named I.V. Michurin were studied for 2012-2013. Study of productivity components was carried out according to the program and technique of variety's study of fruit, berry and nut bearing crops. As a result of the conducted research the high potential of productivity of the studied cornelian cherry varieties in the process of introduction to the Tambov region is established. The range of potential productivity from 1 m of the fructifying wood was from 817,4 to 3170,5 g. Maximum of potential productivity was established for Volgogradskiy Grushevidny. This variety is the most large-fruited also. The average percent of the formed fruits at the studied cornelian cherry varieties is 6,6 % for the period of research. The greatest percent of the formed fruits is noted at varieties of Nakhodka (11,8) and Volgogradskiy (11,0%), the average mass of a fruit is 2,56 g. For the studied period the average productivity of cornelian cherry varieties is 5,1 kg. from a tree. Nakhodka, Nikolka 2 and MOVIR varieties are showed the maximum of economic efficiency in the process of introduction in the Central Chernozyom Region.
