When the collection of winter garlic was transferred from the Urals to Dagestan, there was a change in soil, temperature, water and photoperiodic regimes. Sharp changes in environmental factors lead to the division of the population and the selection of plant morphobiotypes. The obtained values ​​of the coefficient of variation for five quantitative characteristics of four varieties of winter garlic have a relatively small fluctuation (less than 33%), i.e. set of indicators is homogeneous. The greatest variation in characteristics: the mass of one air bulb and the mass of bulbs in the inflorescence. In the mountainous conditions of Dagestan, 18 samples of garlic of winter origin Dagestan, 20 samples of origin Sverdlovsk region, 14 samples from different regions of Russia and 7 samples of foreign countries were studied. The fluctuation of the length of the arrow is small – the coefficient of variation is 12-21%. For other indicators, the variation in values is high, the coefficients of variation were 41-75%. In the mountainous conditions of Dagestan, samples were selected for selection № 30, 66, 240, 486, 487, 488 (origin Dagestan), № 15, 16 (origin Sverdlovsk region), № 319 (Samara), № 10 (Bashkiria), № 105, 263 (Uzbekistan), № 88 (Ukraine).
