Genetic marking of glume color in <Emphasis Type="Italic">Triticum spelta</Emphasis> L. var. <Emphasis Type="Italic">caeruleum</Emphasis> using gliadins

Using gliadins as genetic markers, Triticum spelta L. var. caeruleum accessions were analyzed to identify genetic control of the dark color of glumes. The research material was F₂ and BC₁ plants from crosses between spelt accessions and white-glumed common wheat varieties. The segregation for glume color fitted the monogenic control of the trait. The electrophoretic analysis of gliadins in grains from the hybrid plants has shown that the Gli-Alj* allele in the T. spelta var. caeruleum accessions is linked to the allele for the dark (black) color of glumes at the Rg-A1 locus.
