Diversity of HMW-Glu alleles in landraces and cultivars of winter wheat (Triticui aestivum spelt (Triticum spelta) and emmer (Triticum dicoccoides).

摘要

Among 120 winter wheat landraces and cultivars 224 Glu-lines were identified; in 36 emmer landraces were found 66 lines and a bit lower heterogeneity was recorded in spelt cultivars (17 lines in 10 cultivars). At chromosome lA the allele 2* was rare in wheat (7%) absent in spelt and frequent in emmer (36 % lines). Allele 1 was prevailing in all species (49% in wheat, 82% in spelt and 55% in emmer). Chromosome IB showed high heterogeneity of Glu-alleles in all species. Ten different alleles and/or allelic combinations were found in wheat, most common were 7+9 (40%), 7+8 (22%), 6+8 (16%) and 20 (12%). Combination 6+8 was common also in spelt (76%) and emmer (18%), where alleles 7+8 (41%) and 21 (21%o) were more frequent. Several alleles were found only in emmer. Allelic combination 2+ 12 at ID was common in winter wheat (63% lines ) and spelt (71%), followed by 5+10 pattem. Rare combination 3+12 (4%) was observed only in wheat.
