Assessment of the planting material infection and fungal pathogens identification of garlic

Abstract

The research results of the main diseases that cause garlic bulb rot in the Moscow region during storage are presented. It was shown that long-term storage (17 months), as expected, increased the rots prevalence and development, both Penicilus: 10.0-12.5%, and Fusarium: 10.0-11.3%. Winter garlic cultivar Nina Arsentyevna’s Memory bulbs by 2 species of Fusarium hade been infected: F. fujikuroi and F. roliferatum identified by PCR analysis and subsequent sequencing of the two isolates target genome. Winter garlic cultivar Pamyati Nina Arsentievna is highly resistant to rots of fungal origin, even after long-term storage (more than a year), in comparison with the reference sample from the Federal Scientific Center for Vegetable Growing, the bulbs of which were completely affected, and corresponded to the fifth defeat point. On winter garlic, the causative agent of penicillium rot, Penicillium glaucum Link, was also found. On collection samples of winter garlic, during selective annual studies, penicillary rot was not found.
