Abstract

The occurrence of two types of cultivars of spring bread wheat of Canada that differ in their necrotic genotypes was shown. The cultivars of one type had the ne1ne1Ne2Ne2 genotype, and the cultivars of the second type had the ne1ne1ne2ne2 genotype. The Ne1Ne1ne2ne2 genotype was not found. The Ne2 genes were represented by medium strength, ms, and strong alleles, s. By pedigree analysis, the donors of the Ne2 gene were identified.
