On the basis of allelic frequencies at the seven loci, genetic distances between hexaploid triticales grouped according to their origins revealed two groups: winter triticales mostly originating from European germplasm and spring triticales essentially of CIMMYT origin.
Glu-B1 and Glu-B3 loci were the most polymorphic with 9 alleles each. Analysis by SDS-PAGE of the majority of hexaploid triticales (69 cultivars) grown in France allowed to identify 36 alleles at seven loci: Glu-A1, Glu-B1, Glu-R1, Gli-R2, Glu-B2, Glu-A3 and Glu-B3.
Although the endosperm storage protein of hexaploid triticale have already been analysed, the allelic diversity of glutenins and secalins remains to be described.
