The results of 2-year studies concerned the estimation of some onion cultivars in cultivation for sets. An experiment was conducted in the field conditions. It compared the height and structure of the total and marketable yields of bulb sets of the most important Polish cultivars (‘Wolska’, ‘Rawska’, ‘Sochaczewska’, ‘Czerniakowska’, ‘Kristine’, ‘Efekt’, ‘Kutnowska’, ‘Błońska’, ‘Żytawska’) and the Dutch cultivars recommended for the production of onion sets (‘Centurion F1’, ‘Picko Bello’ and ‘Red Baron’). Besides, the storage ability of sets of those cultivars was studied in different storage conditions (temperature 0°C and 18°C). Considering the height of the bulb sets yield, a high proportion of small bulbs with a diameter not greater than 15 mm, and low storage losses, the best cultivars included ‘Centurion F1’, ‘Picko Bello’, and ‘Rawska’. Among the studied cultivars, ‘Red Baron’ had the worst storage ability as very many bulb sets became completely dried up and infected with diseases. Because of high losses of bulb sets stored at a temperature of about 18°C, very small sets should not be stored in such conditions since they do not require any special protection against bolting.
