Fusarium basal rot of onions causes large losses during storage of commercial production of onion bulbs, which in turn adversely affects the food market situation in the off-season period. There are no data on the composition of Fusarium spp., which causes onion basal rot in the Russian Federation. Therefore, our research was aimed at Fusarium spp. causing onion basal rot in the Moscow Region of the Russian Federation and studying the pathogenicity of these species for the host plant. We studied 20 isolates of Fusarium spp. collected from affected mature bulbs and seed bulbs. Species identification of the isolates was carried out using analysis of the nucleotide sequences of the three genetic loci ITS, tef1 and rpb2, as well as was based on the macro- and micromorphological characteristics of these isolates. As a result, the species F. annulatum (F. fujikuroi species complex), F. oxysporum (F. oxysporum species complex), F. acuminatum (F. tricinctum species complex) and F. solani (F. solani species complex) were identified to involve in the pathogenesis of Fusarium basal rot. We have shown for the first time that the species F. annulatum and F. acuminatum are highly aggressive and capable of causing onion basal rot. The predominant species were F. annulatum and F. oxysporum. The proportion of these species in the total number of analyzed isolates was 60% and 25%, respectively. The largest proportion (33%) of highly aggressive on mature bulbs isolates was found in the species F. annulatum. The data obtained provide practical insights for developing strategies to manage Fusarium fungi responsible for onion basal rot Moscow Region of the Russian Federation. In addition, data about species composition and aggressive isolates may be used in onion breeding for resistance to Fusarium basal rot.

Relevance. The success of breeding work is largely determined by the source material, the search and creation of which for target breeding begins with the collection and study of collectible samples for the alignment of morphological features; for the precocity and amity of maturation; for the keeping quality and transportability of bulbs; for the quality of vegetable products (high content of biologically active substances and antioxidants); for resistance to biotic and abiotic stressors of a specific growing zone.Materials and methods. On the basis of the North Caucasus branch FSBSI FSVC, 90 samples of spring onions from 26 countries of the world were evaluated in the number nursery for the period from 2017 to 2019, 71 of them were varieties and 19 were F1 hybrids. In a hybrid nursery, 25 hybrid combinations obtained from FSBSI FSVC (VNIISSOK) were evaluated. The laying and placement of experiments, agricultural techniques of cultivation, accounting and evaluation of economically valuable traits, biochemical analyses were carried out according to generally accepted methods. The standards are the new Primo and Ampex varieties of the selection of the FSBSI FSVC and the Italian F1 hybrid Ranko, which were placed every 10 collection samples.Results.According to the results of the assessment, among the studied F1 varieties and hybrids, sources of economically valuable traits such as yield (20-27 t/ha), precocity (80-90 days), preservation (more than 85%) when laid for long-term storage up to 7 months, purple, white and pink color of bulbs, as well as sources of long-shaped bulbs were identified. The greatest interest for breeding for yield is represented by 9 promising varieties and 9 F1 hybrids of onions of various origins, as well as 4 hybrid combinations that were distinguished by high yields, the yield of marketable products and the mass of marketable bulbs. These samples are recommended for use in the breeding process as sources for the creation of new varieties and hybrids with high yields for the agro-climatic conditions of the foothill zone of the North Caucasus.r breeding

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.
