Короткий опис(реферат):
Випробування сортів картоплі впродовж трьох років дозволило виявити їх потенціал за проявом продуктивності. Лише між окремими варіантами не встановлено істотної різниці у вираженні показника. Виділені сорти, які в певних умовах характеризувалися стабільною продуктивністю, а, отже, мали низький коефіцієнт варіації. Представлены результаты исследования, доказывающие влияние внешних условий (метеорологических и почвенно-географических) на реализацию потенциала сортов по продуктивности. Установлено отсутствие существенного различия проявления признака только среди некоторых вариантов. Лишь у отдельных сортов в определенных условиях выявлено минимальное значение коэффициента вариации.

Under stability of soil conditions during research in both academic establishments it was marked the significant differences in the revealing of weather conditions which certainly affected the yield capacity. Under conditions of SNAU extreme temperature was observed for two months in 2012 and for three ones in 2013, and under Ustymivska research station extreme temperature was fixed the for all vegetative period besides August 2011 and July 2013. In the specific conditions of the study it was able to establish the norm of reaction of genotypes on these factors.
Only in Picasso variety in 2013 was fixed higher yield capacity for the estimation in SNAU. Zagadka, Zabava, Lastivka, Cherwona ruta, Teteriv and Picasso varieties under favorable conditions showed the high potential concerning yield capacity; this indicator reached 1000 g /plant, for Chervona ruta and Zagadka varieties it was 1600 g / plant. Tests took place in 2011 (Ustymivska Experiment Station).
Among four variants it was not found significant difference in yield capacity that confirmed a significant distinction in symptoms revealing depending on the biological characteristics of varieties and cultivation conditions. For Lastivka and Raja varieties in experiments on Ustymivska station it was found relatively low value of the variation coefficient (10%) but for the most varieties it exceeded 40 %. Under conditions of SNAU for Kosen 95, Chervona ruta varieties the coefficients were 64 and 66%.
