Descripción
The allelic variation at seven prolamin loci involved in durum wheat quality was studied in a set of landraces from all the Spanish provinces where durum wheat was traditionally cultivated. The genetic variability found was greater than that found in other germplasm collections. All the loci, except Glu-B2, displayed a genetic variability larger than 0.62, with Glu-3 the most polymorphic. In total, five alleles were studied at Glu-A1, nine at Glu-B1, 15 at Glu-A3, 18 at Glu-B3, two at Glu-B2, and eight at Gli-A1 and Gli-B1. New allelic variants not previously identified in durum wheat were found. The 30 different LMW genotypes analysed, of which 25 are novel, provide an important source of genetic variability for quality breeding. Protein patterns for convars. durum and turgidum, and for the South and North of Spain were found for the loci with significant influence on quality. Wider variability was observed in convar. turgidum and in the North zone than in convar. durum and the South, respectively, mainly for the loci on chromosome B. Also, convar. turgidum appeared to be a valuable source for new alleles for the B-LMW glutenin subunits. Wheats from the South were, however, more diverse for prolamins encoded at Glu-A3.
