Description
Summary:In the Republic of Komi (Russia), one of the main agricultural vegetable crops cultivated by agro-enterprises, peasant farms and the population in the private sector is potatoes. The food security of Russia in the Arctic zone and obtaining competitive varieties for the regions of the Far North of our country is the main task solved by agricultural science in the field of breeding. New, promising varieties of potatoes must meet modern requirements for high yields obtained in various natural, soil and climatic conditions of their cultivation. In addition, varieties should have high stability in terms of commercial and economic characteristics and give an equivalent yield in constantly changing environmental conditions, both for the better (favorable) and for the worse (unfavorable). The use of modern methods of mathematical, statistical analysis, calculation of the assessment of environmental stability, plasticity, adaptability, as well as an objective and complete assessment of the potential of potato genomes, rigorous selection of promising lines and hybrids and screening for various negative traits, especially at the first stages of breeding, variety samples that do not correspond and do not satisfy these parameters, allow you to quickly obtain new varieties adapted to the Arctic zone of the Russian Federation. In order to strengthen breeding work aimed at breeding promising varieties of potatoes, in 2020-2022, a research program was carried out in breeding nurseries of the dynamic competitive first, second and third years of testing (hybrids of the sixth, seventh and eighth tuber generation) on the basis of the Institute of Agricultural Biotechnology of the Federal Research Center Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences (Russia, Syktyvkar). New promising potato hybrids (varieties) were selected as the object of study: 2341-265 (Amur x Gala), 2339-8 (Oksania x Gala), 2339-9 (Oksania x Gala), 1992-14 (Udacha x Elmundo), 2000-60 (Colette x FZ 1867); the standards were zoned ...
