  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>A collection of isolates of the fungi <jats:italic>Leptosphaeria maculans</jats:italic> and <jats:italic>L</jats:italic>. <jats:italic>biglobosa</jats:italic>, which cause blackleg disease on <jats:italic>Brassica napus</jats:italic> (canola/oilseed rape) and other <jats:italic>Brassicaceae</jats:italic> species, was assembled to represent the global diversity of these pathogens and a resource for international research. The collection consists of 226 isolates (205 <jats:italic>L</jats:italic>. <jats:italic>maculans</jats:italic> and 21 <jats:italic>L</jats:italic>. <jats:italic>biglobosa</jats:italic>) from 11 countries. The genomes of all 205 <jats:italic>L</jats:italic>. <jats:italic>maculans</jats:italic> isolates were sequenced, and the distribution and identity of avirulence gene alleles were determined based on genotypic information and phenotypic reactions on <jats:italic>B</jats:italic>. <jats:italic>napus</jats:italic> lines that hosted specific resistance genes. Whilst the frequencies of some avirulence alleles were consistent across each of the regions, others differed dramatically, potentially reflecting the canola/oilseed rape cultivars grown in those countries. Analyses of the single‐nucleotide polymorphism (SNP) diversity within these <jats:italic>L</jats:italic>. <jats:italic>maculans</jats:italic> isolates revealed geographical separation of the populations. This "open access" resource provides a standardized set of isolates that can be used to define the basis for how these fungal pathogens cause disease, and as a tool for discovery of new resistance traits in <jats:italic>Brassica</jats:italic> species.</jats:p>
