Abstract
The aim of this study was to determine the composition of HMW glutenin alleles at the loci Glu-A1, Glu-B1 and Glu-D1 in introgressives derived from interspecific hybrids of various strains and varieties of Triticum aestivum L. and Triticum durum Desf. For locus Glu-A1, the following subunits were detected: 1 (16.9%), 2* (20.3%), and the null subunit N (62.7%). These subunits are coded for by the alleles a, b and c, respectively. For locus Glu-B1, the following subunits and subunit combinations were detected: 7 (18.6%), 7+8 (15.2%), 7+9 (47.4%), 6+8 (15.2%), 6+7+8 (1.7%) and 6+7+8+9 (1.7%). The first four subunit pairs are coded for by alleles a, b, c and d, respectively...
