In Canada, several pathotypes of this pathogen, such as pathotype 2, 3, 5, 6 and 8, were identified, and resistance to these pathotypes was found in a rutabaga ( B. napus var. napobrassica ) genotype. In this paper, we report the genetic basis and molecular mapping of this resistance by use of F 2, backcross (BC1) and doubled haploid (DH) populations generated from crossing of this rutabaga line to a susceptible spring B. napus canola line.
