In commodity farms, the technology of growing onions by sowing from seeds in an annual crop is spreading. However, the average yield of onions in Russia is at a low level: 20–30 t/ha. New varieties and hybrids should have early maturity, high yield, resistance to diseases and pests, and good keeping quality. In the State register of breeding achievements of the Russian Federation, approved for use in 2020, 385 varieties and hybrids of onions are registered, including 195 varieties and 190 hybrids. In 2020, eighteen new hybrids and one variety are included. Along with the creation of heterotic hybrids in the moment in the Department of breeding and seed production of the All-Russian Research Institute of Vegetable Growing – branch of Federal Scientific Centre of Vegetable Growing (ARRIVG – branch of FSBSI FSVC) also continues the selection of varieties that show high performance when grown in annual crops. The aim of the work is to evaluate promising samples of onions in a competitive nursery. The research was carried out in 2019–2020 in the Moscow region at ARRIVG – branch of FSBSI FSVC. Experiments were carried out according to generally accepted methods. Seeds were sown on April 24 with a precision seeding machine Gaspardo Olimpia on a ridge of 1.4 m according to a two-line three-row scheme, with a distance between the lines of 8 cm. The seeding rate is 0.8 million pieces/ha of germinating seeds. The accounting area of the plot is 98 m2, the repetition of the experience options is three-fold. The lack of moisture during the growing season was compensated by irrigation through a drip irrigation system, maintaining the HB at the level of 80–85%. The object of research is promising samples of onion Sn-20/16 and Al-20/16. As a standard, the Forward variety was used. The testing results showed that the varieties Sn-20/16 and Al-20/16 are promising for the Moscow region, as they have a high yield potential and high quality of bulbs.
