Wild Panax ginseng C.A. Mey. (Araliaceae) is a rare medicinal plant. The purpose of the research was to assess genetic diversity of productive and morphofunctional characteristics of ginseng plants in scientific and industrial plantation. The research problem was studying individual variability and the analysis of correlation interrelation of root weight and structurally functional characteristics of 60 plants of ginseng cultivated for six-years. A wide variation was found on root weight (9.7-95.7 g, CV - 43 %), on seeds number (13-146, CV - 48 %), on the length of the main root - from 1,5 to 15,0 cm (CV - 57 %) and to the quantity lateral (from 1 to 10, CV - 42 %) and subordinate clauses (from 0 to 7, CV - 53 %) roots. The parameters of the biomass structure also varied significantly, reflecting the diversity of donor-acceptor relations’ types and morphotypes of ginseng plants on the plantation. The fruits index was more variable CV - 37 % and root index was the most conservative CV - 10 %. The analysis of correlation interrelation of weight of the root and morphofunctional characteristics of plants revealed rather high positive communication with thickness of the main root (r = 0.66, p < 0.05), the number of lateral roots (r = 0.45, p < 0.05) and the area of the leaves on a plant (r = 0.61, p < 0.05). High negative correlation of root weight was observed with leaves index of (r = 0.65, p <0.05). The variety of genotypes presented on the plantation on the efficiency, the morphotype of plants and morphology of roots testified to the possibility of carrying out selection works on creation of a productive seaside variety of a ginseng. By the results of the researches perspective signs for selection can be the thickness of the main root, the number of lateral roots and the area of leaves of plants of ginseng.
