ALLELIC VARIATION AT GLU-1 LOCI IN SOME YUGOSLAV WHEAT CULTIVARS

The high molecular weight (HMW) subunits of glutenin extracted from fl our of 36 Yugoslav wheat cultivars were separated by SDS-PAGE to ident ify their alleles, and the frequency of each allele was calculated. El even alleles from the three Glu-loci were recognized, three at the Glu -A1 locus, six at the Glu-B1 locus and two at the Glu-D1 locus. The mo st frequent allele was ''a'' (55.5%) from Glu-DI, which controls synth esis of subunits 2+12. The Glu-1 quality score varied from 4 (KG-III/2 7, KG-75, Morava and KG-101/7) to 10 (Lepenica). The mean Glu-1 qualit y score of cultivars and lines from Kragujevac was 6.8, for cultivars from Zagreb 7.2, and for cultivars from Novi Sad was 7.9. Most of the genotypes with a quality score of 8 or above, had high sedimentation v alues (Zeleny test). There were no significant differences in allelic composition at the Glu-1 loci among wheat genotypes from Kragujevac, N ovi Sad and Zagreb.
