Research results of local samples of winter garlic in the Republic of Dagestan

Abstract

The collection of winter garlic from Yekaterinburg was transferred to the Federal Agrarian Research Center of the Republic of Dagestan. The Ekaterinburg collection contained specimens of Dagestan origin; when transferred to Dagestan, it was significantly expanded with local forms. Total studied in 2021-2022 60 samples, all of them belong to the group of autumn shooters. According to the average mass of bulbs over 20 g, seven samples were distinguished: 1-4-3, 1-20-2, 1-20-3, 1-21-3, 1-21-4, 2-5-3, 2-9-2. They also noted the largest masses of bulbs – 25,8- 30,4 g, the coefficient of variation did not exceed 33%. For reproduction by air bulbs, taking into account their number and weight of the bulb, out of seven samples marked by the mass of the bulb, three were distinguished: 1-4-3, 1-21-4 and 2-9-2, the indicators exceed the average values. According to the maximum mass of an air bulb (150 mg), sample 1-22-2 stood out, but this sample had an average bulb weight of 13,9 g. Sample 2-13-1 also exceeded the average values for the number of bulbs and bulb mass, but it had an average bulbs less than 20 g and a coefficient of variation of 41%. The results of studying the collection of Dagestan origin showed that the samples represented a complex population with high differentiation in bulb mass and inflorescence characteristics, which made it possible to isolate the source material using individual selection. According to the average mass of bulbs, samples 1-4-3, 1-20-2, 1-20-3, 1-21-3, 1-21-4, 2-5-3, 2-9-2 were distinguished, of which for propagation by air bulbs –samples 1-4-3, 1-21-4 and 2-9-2.
