Allelic variation at high molecular weight glutenin loci associated with superior breadmaking characteristics in hexaploid introgressives of Triticum aestivum L. and Triticum durum Desf.

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...
