Abstract
Black rot (caus. agent Xanthomonas campestris pv. campestris (Dowson) Dye, et al. (1980) is the most harmful disease of brassicas, widespread across the World. Plant breeding for resistance to Xcc received a new push after the discovery a racespecific reaction in several plant species of the Brassicaceae family in 1992 and, accordingly, the racial structure of the pathogen population. The number of pathogen races (11 at the moment) and putative resistance genes is constantly increasing,
which makes it difficult to breed plants following a complex model describing the gene-to-gene relationship between the pathogen and plants. The developed molecular markers of resistance genes and pathogen races do not yet give a reliable result due to the high genetic diversity of populations. This review identifies the main tasks and suggests possible ways to solve them.
