Onion crops cover more than 95% of the area under all types of onions. Due to its high taste and nutritional qualities, it is one of the most common vegetable crops in our country-it occupies 64 thousand hectares and is in third place, behind cabbage and tomato. The increase in onion production is not only due to an increase in the area occupied by the crop, but also due to an increase in yield. This is achieved by introducing new highly productive varieties and hybrids into production, increasing the overall culture of agriculture and the level of cultivation technology. Along with the creation of heterotic hybrids, the selection of varieties that show high rates when grown in an annual crop is currently continuing. The purpose of the research: to test samples of onions of different geographical origin in an annual crop; to evaluate the main economically valuable characteristics and to identify the most adaptive sources for the main parameters. Environmental testing of 18 samples of onions of domestic and foreign selection was carried out in 2019–2020 at the experimental site of the Department of selection and seed production of ARRIVG – branch of FSBSI FSVC research center for vegetable growing with the staging of experiments in the open ground. During the growing season, phenological, biometric measurements and morphological description of samples were performed in accordance with the guidelines «Study and maintenance of the world collection of onions and garlic». As a standard, the Forward variety of domestic selection and the foreign F1 hybrid Premito were used. The intensity of wax coating on the samples was assessed visually. Samples were identified as sources of economically valuable traits: 13 samples were identified for the round and round-flat shape of the bulb, 6 samples were identified for the yellow-brown color of dry integumentary scales, and 7 samples were identified for the dry matter content above 11.0%.
