Altynkolsky onion in the cultural conditions of the Moscow region

The wild-growing forms of the Urals, Siberia, Central Asia, local ancient populations, and samples introduced from other ecological and geographical zones for a long time are of undoubted value to create new, locally adapted varieties of onion crops. A comprehensive study of the biological characteristics of species of the genus Allium during introduction allows us to expand the range of these perennials used for food and decorative purposes, and thereby enrich the biodiversity of the cultural flora of Russia. Altynkolsky onion (A. altyncolicum N. Friesen) grows in Southern Altai, it is narrow-local endemic, mesogygrophyte. Selection forms of altynkolsky onion still do not exist. The object of the study was a collection of A. altyncolicum from six samples of various origins. Experiments were carried out to study and describe the biological and economic characteristics of Altynkolsky onion. In the conditions of the Moscow region, Altynkolsky onion is characterized by winter hardiness; it is not damaged by spring and autumn frosts, and no damage by pests is noted. Clones No. 2 and No. 5 were distinguished, which are distinguished by a large number of shoots and leaves, yields of 3.1-3.2 kg/m2 per cut. At that they are characterized by resistance to rust (Puccinia alli (DC.) F. Rudolphi), relative resistance to peronosporosis (Peronospora destructor (Berk) Casp.), as well as high winter hardiness. In the economic maturity phase, the dry matter content in the leaves averaged 17.9 %, the dry matter content in the leaves averaged 17.9 %, ascorbic acid 128.8 mg%, carotene 23.7 mg/kg wet weight, hydroxycinnamic acids 174 x 10-3 % and flavonoids 295.2 x 10-3% dry mass. Clone selection allowed us to create new source material promising for further breeding work.
