Abstract
Gluten content, and more importantly its composition expressed through glutenin subunits, has great influence on the rheological and bread-making properties of wheat flour. Total of 168 winter wheat cultivars developed at the Institute of Field and Vegetable Crops, Novi Sad, Serbia in the period 1987-2008 were analysed for high molecular weight glutenin subunits (HMWGS) composition using SDS-PAGE. Presence of twelve different alleles and nineteen different GS combinations was determined. The highest frequency was found for GS N at the locus Glu-A1 (46%), 7+9 (77%) at the locus Glu-B1 and 5+10 (72.7%) at the locus Glu-D1. The most frequent combination was 2*, 7+9, 5+10. Presence of several rare GS with positive effect (13+16 and 15+16) was determined, as well as high uniformity of the genetic material, considering small number of cultivars (4.2%) with different electrophoretic paths. Two modes of glutenin score (Glu-1 score) determination were applied, based on which differences in bread-making quality among individual cultivars can be determined more precisely.Keywords
