To solve the problem of year-round supply of fresh carrots to the population, it is neces-sary to have varieties that retain high commercial qualities for 220-250 days of storage [1, 2]. The resistance of root crops to diseases significantly affects the profitability of their sale after storage (r=-0.64). In large agricultural holdings and small farms, foreign varieties and hybrids are often used, betting on yield. However, the profitability of sales after long-term storage is mainly higher for varieties and hybrids of Russian breeding, due to the least losses of commer-cial root crops during long-term storage. Compared with stable ones, the profitability of the sale of unstable samples decreases by 2.6 times at a 20-30% level of root crop damage, and at a 40% lesion - by 28 times [3].  The pathocomplex of storage diseases (cagate rot) is represented by a wide range of pa-thogens, the composition and ratio of which varies depending on the year, variety and place of cultivation [4]. Along with the increasing aggressiveness of local races of pathogens, new races have been introduced in recent years [4]. Therefore, one of the main requirements of modern breeding for immunity is the search for sources of resistance not only to a separate, but also to a complex of pathogens of the cellular rot. In this regard, monitoring the spread of storage diseases in the carrot culture of the canteen and the search for such sources is always relevant and is the goal of our work.
