The article deals with the issues of selection and seed production of onion (Allium cepa L.). Breeding studies were conducted in the nursery of the Belgorod state agrarian UNIVERSITY in 2016-2017. The influence of the fraction size on the yield and structure of onion crops (Allium cepa L.) was studied. it was found that plants in the 1st and 2nd families performed better when planting a large fraction of sowing. The yield in these variants was 2.76-3.05 kg / m2, the density of crops was 172-191 plants per 1 m 2 . Skirmished plants were not observed when planting a large fraction of onion-sowing. Thus, it is recommended to use samples of these 2 families to continue the selection process.
