The study of the source material in order to select promising forms for creating new varieties adapted to the conditions of Dagestan is of great practical importance and will significantly increase the production of winter garlic. In 2022-2023, 35 samples of local winter garlic were tested at the Federal Agrarian Scientific Center of the Republic of Dagestan. Small (less than 20 g) bulbs were obtained from 9 samples, medium (20-35 g) – from 20 samples, large (more than 35 g) – only from 6 samples. The variability of bulb weight indicators of less than 33% was observed in the medium fraction in 8 samples out of 20, and in the large fraction - in 4 samples out of 6. In all samples, the number of cloves in the bulb was less than 15 pieces The coefficient of variation in the number of cloves exceeds 33% only in 3 samples out of 35, the rest have a homogeneous population for this indicator. In medium-weight bulbs, small diameter (2,1-3,0 cm) was noted in 2 samples, medium (3,1-4,0 cm) – in 3 samples. Bulb diameter over 4,0 cm was observed in 3 samples. The number of aerial bulbils of garlic is a varietal trait, this indicator is variable and in all analyzed samples the number of bulbils varies from 25,0 to 110,0 pcs., the variability of the indicator exceeds 33% in 10 samples out of 35. The weight of the aerial bulbil of all samples fluctuates within 13,3-60,0 mg. Samples 1-18/4, 1-22/3, 267-T, 1020-T stood out for the weight of the bulb exceeding 40 g with a homogeneous population. For propagation by aerial bulbils with a bulb weight of 22,0-41,1 g, a number of bulbils of 70,0-108,4 pcs., and a bulb weight of 20.0-40.0 mg, samples 1-18/4, 2-9/2, 2-10/4, 194-T, and 433-T were selected.
