ECOLOGICAL PLASTICITY OF POTATOES CULTIVARS IN TYUMEN REGION
The authors studied the ecological plasticity of the registered potatoes cultivars in Tyumen region. It was found that in the hot and dry year 2012 Nevsky, Sarma and Severniy cultivars showed increased yield (23.6 - 31.8 tons/hectar). The years of research revealed consistent yields of Red Scarlett, Rosario and Sarma cultivars. The Early Zhukovsky, Severniy and Tuleevsky cultivars are characterized by high ecological plasticity. Sarma and Tuleevsky cultivars have outstanding palatability.
