Abstract

The parameters of adaptability and stability of the genotype on the basis of productivity in 14 varieties of potatoes of domestic selection were evaluated. The research was carried out in the fields of the Samara Scientific Research Agriculture Institute in 2019-2022 under conditions of moisture deficiency and high air temperature. According to the average yield over the years of research, medium-early varieties of Krasa Meschery, Debut, Sudarinya, as well as medium-ripe Siversky and Alaska were distinguished. The most balanced indicators of plasticity and stability when using two different methods for their evaluation were found in the Debut variety. The varieties Plamya, Legenda, Sudarinya and Signal are also distinguished as valuable genotypes. It was found that the value of the variety in the agroecological conditions of the research area was primarily determined by indicators of crop stability in different years. Environmentally plastic and neutral potato varieties may have an advantage in these conditions.
