Adaptive potential of grades of potatoes in the conditions of Kamchatka Krai. G.P. VLASENKO (Kamchatka
Scientific Research Institute of Agriculture, Kamchatka Krai, Yelizovsky District, Sosnovka village).
The comparative analysis of ecological plasticity and stability of perspective varieties of potatoes is presented
in the article. During the test period (2013–2016) the most fruitful were the following varieties: Yugana, Ladozhskiy
(28.3 t/ha), Madeline (28.6 t/ha), Radonezhskiy (31.3 t/ha), Safo (30.3 t/ha), Geyzer (28.7 t/ha). The absolute measure of
adaptability coefficient of these grades is more than a unit: from 1.01 (Yugana, Ladozhskiy) up to 1.11 (Radonezhskiy).
On the basis of the conducted analysis the following varieties are referred to an intensive type: Radonezhskiy, Madeline,
Safo (bi = 1.29–1.51) and the following varieties are referred to a plastic type: Geyzer, Yugana, Ryabinushka, Ladozhskiy,
Rucheek, Aurora (bi = 0.73–1.02). The most stable varieties were Radonezhskiy and Geyzer, annualized stable varieties
were Rucheek and Aurora, but their productivity was 2.0 and 2.1 t/ha lower than the average by experience. From the
studied group of varieties, taking into account the complex of economically valuable features, it is expedient to grow up
domestic, intensive varieties Radonezhskiy, Safo and plastic varieties Geyzer, Yugana.
