The purpose of the present research was: to study the collection nursery of bulb onions on the main economic valuable features in the conditions of the Astrakhan region. The research was carried out in the conditions of the 2017–2018 vegetation in the Chernoyar district, on the experimental section of the Caspian research Institute of Arid agriculture, located in the north-western part of the Astrakhan region. Soils on the areas of the studied zone – light chestnut, different degree of salt content, occupy a dominant position in the soil cover of the considered territory. On the whole, weather conditions were unfavourable for the cultivation of bulb onions. The experiments were laid down in accordance with the generally accepted methodologies according to bulb onions agricultural machinery in the Astrakhan region. For research in 2017–2018 samples from the genetic collection VIR named after N.I. Vavilov were used, as well as samples taken in previous years. The collection nursery of bulb onions was represented by 50 samples, 26 of them stood out during the years of research. Sowing of seeds of collector nursery of bulb onions was carried out in one term: on May 3 (in all years of research). Results were obtained for selected samples of the collection nursery of onion by phenological phases. Mass shoots were observed on 12–22 days from sowing. The phenological phase «the beginning of the formation of the follicles» was noted in 61 to 68 days from sowing. Early-maturing examples of onions in the collection nursery include: Sorokozubka, Suttons improved, Red mom, Northern. During the years of study, red Extra, Markovsky, Vertus, Selfed, Jetset, and Sillani Sargo showed themselves to be the middle-aged samples. According to the main economically valuable features, 15 collection samples were distinguished. According to the selected samples of onion, the average yield was noted in five samples: Maravanka, Almadon, Southport, Selfed, Local (Georgia), the average weight of the commodity bulb was 151.6 g. Аccording to the commodity yield, three collection samples were distinguished: Zillani, Suttons improved, Encore. In the Markovsky variety, 70% of commercially Mature bulbs were observed. The maximum mass of a commodity bulb of 206.0 g was noted in the collection sample of Cebola.
