DETECTION OF LMW GLUTENIN ALLELIC COMPOSITION IN GLU-A3 LOCI OF WHEAT (TRITICUM AESTIVUM L.) WITH NON-STANDARD COLOR OF CARYOPSIS

Using 7 specific STS markers, allelic composition of Glu-A3 locus was examined among set of 36 winter wheat genotypes containing blue, purple, yellow and red caryopses. Allele Glu-A3d occurred in all analyzed samples. Together with the Glu-A3d allele were detected Glu-A3f (53%) and Glu-A3c (8%) alleles. Two heterozygous gene forms were detected in wheat collection (Glu-A3d/f and Glu-A3c/d). Other Glu-A3a, Glu-A3b, Glu-A3e and Glu-A3g alleles were not detected in any sample. Selected yield and quality characteristics are also presented. Lines with non-standard caryopsis color had lower yields in comparison with standard ones. Group of lines with purple pericarp had high falling number which is connected with low activity of the hydrolytic enzymes and good resistance to sprouting. The non-standard color of the caryopsis is determined by anthocyanins and carotenoids which are important antioxidants.
