Abstract
The Swedish black currant Ojebyn is heterozygous for a dominant gene, designated Sph2, conferring effective resistance against Sphaerotheca mors-uvae at East Malling. Resistance due to the gene M derived from the Finnish Brodtorp is now often only partial and in some progenies is associated with an undesirable spreading habit. Size differences in the satellites of the two nucleolar chromosomes of Brodtorp are not closely associted with differential mildew response in its derivatives.
