Abstract. The article presents the results of the study of ten new varieties of potato of German breeding from different maturity groups according to their ability to form a yield in agro-climatic conditions of the Middle Volga region. Weather conditions during the study period (2013-2015) were contrasting and had significant deviations from the average long-term rates. The soil type of the experimental plot was gray forest, heavy loamy, the content of humus was 3.2 %, of alkali-hydrolysable nitrogen – 101 mg/kg, of mobile phosphorus – 290 mg/kg, of exchange potassium – 180 mg/kg; рН of salt extraction was 5.8. Sandrin variety distinguished according to the average productivity (48 t/ha) in the group of early-maturing forms; Oxania variety – among the middle-early forms (48 t/ha). These varieties were characterized by the high stability of yield formation: the coefficient of variation (Cv) was 8.3 % and 5.5 %, stability index (IS) was 5.8 and 8.7, and criterion of the level and stability of yield of a variety (Clsv) was 589 and 877, respectively. According to the number of tubers per plant in the group of early-maturing forms it was distinguished varieties Serafina (12.3 tubers/plant), Fioretta (11.6 tubers/plant) and Sandrin (11.3 tubers/plant); in the group of middle-early forms – varieties Caprice (9.8 tubers/plant), Damaris (9.1 tubers/plant) and Florence (9.1 tubers/plant). The high stability of this trait was revealed in varieties Axenia (Cv is 6.3 %, IS is 1.2, Clsv is 116) and Caprice (Cv is 7.8 %, IS is 1.3, Clsv is 145). Cultivars Sandrin and Axenia had the highest average weight of marketable tubers among the early maturing varieties (256 g and 235 g, respectively); cultivars Damaris and Oxania – among the medium early forms (263 g and 242 g, respectively). Variety Oxania was characterized by high stability of weight of marketable tubers (Cv was 5.6 %, IS was 43.6, Clsv was 4850). According to the results of the study it was selected the plastic variety Serafina of an intensive type (maximum tuber yield of 59 t/ha) with the highest expression of the studied traits under favorable agro-climatic conditions, as well as stable cultivars Sandrin and Oxania with a stable yield formation under contrasting weather conditions.
