COMPLEX FEATURES OF Allium oschaninii O. Fedtsch. FOR TESTING FOR DISTINCTNESS, UNIFORMITY AND STABILITY

Allium oschaninii O. Fedtsch. is distributed in the middle belt of the Pamir and Altai mountains. The local population uses leaves and bulbs for food in fresh and canned form. Selective forms of onion Oshanina still does not exist. The research was carried out in the AllRussian Research Institute of Vegetable Growing a branch of the Federal State Budget Scientific Institution "Federal Scientific Center for Vegetable Growing" (VNIIO branch of FGBNU FNCS) in 20142017. The object of the study was a collection of five samples of A. oschaninii O. Fedtsch. of various origins. Experiments were conducted to study and describe the biological and economic features of onion Oshanin (Allium oschaninii O. Fedtsch.) In the Moscow region; statistical processing and analysis of research results; methods for describing the characteristics used to assess distinctness, uniformity and stability are given. The object of the research was a collection of five samples A. oschaninii O. Fedtsch. of various origins. Methodical recommendations for registration of onion Oshanin (A. oschaninii O. Fedtsch.) In the State Register of Selection Achievements, admitted to use in the territory of the Russian Federation, for introduction into culture and introduction into production, are developed. The methodological recommendations have been prepared in accordance with the principles of similar methods used in UPOV and the State Commission of the Russian Federation for Testing and Preservation of Selection Achievements. A system of parameters has been developed, the use of which will ensure the contribution of new knowledge to the theory and practice of seed selection and production, will help to speed up the development of new varieties and hybrids with high winter hardiness, with early and harmonious growth of leaves, a long period of preservation of commercial qualities of green products resistant to peronosporosis for the Non-chernozem zone of the Russian Federation, to assess the effectiveness of selection work in order to increase yields, improve product quality and increase the resistance of new varieties to the impact of factors on of the circling medium. The results of the research can be used in breeding organizations and state stations, in the description of new varieties based on the characteristics used to assess distinctness, uniformity and stability.
