The cultivation of perennial onions may increase the availability of green leaves in the early spring period and reduce the problem of vitamin deficiency. Welsh onion (Allium fistulosum) is one of the most demanded crops of the perennial onion group both in commercial and household vegetable growing. This is quite low maintenance crop with a number of positive qualities and properties. The factor that constrains the spread of this crop and its most intensive introduction in commercial growing is the lack of varieties adapted to the growing conditions. The plant breeders of the Altai Region have made major efforts for collecting the source material of Welsh onion, studying it further and conducting the selection. As a result, the clones with economically valuable characters were selected from the candidate varieties. In 2016, the candidate variety No. 44 was submitted to the State Variety Testing, it went through the trials successfully, and was included in the State Register of Selection Achievements as Premyera variety. The variety is middle-ripening, the period from the mass regrowth of leaves to the beginning of economic life is 20-28 days. One of its main practical advantages is late formation of flower shoots (4-14 June), which makes it possible to extend the period of economic validity of landings. According to the results of tests, on average for three years, the new variety in marketable yield exceeds the standard Nezhnost with a onetime cleaning per year of sowing by 32.2% and with cuttings in perennial crops by 39.7%.
