Genetic marking of glume colour in Triticum spelta L. var. caeruleum using gliadins.

Abstract

Genetic control of dark color of glumes was studied in Triticum spelta L. var. caeruleum accessions using gliadins as genetic markers. F2 and BC1 plants from crosses between the spelt accessions and common wheat varieties with white glumes served as the material for the investigation. Analysis of segregation for glume colour fitted the monogenic control of the character. Using electrophoretical analysis of gliadin of seeds from the hybrid plants it was revealed that in the T. spelta var. caeruleum accessions the allele Gli-A1j* is linked to the allele for dark (black) glumes at the Rg-A1 locus.
