The method of PAGE was used to determine isozyme variability of esterases in the barley cultivars originated at the Institute of Field and Vegetable Crops in Novi Sad (Yugoslavia), as well as the possibility of their use in barley cultivar identification. Five isozymes were expressed. Loci Est2 and Est6 were monomorphic, Est1 and Est4 had two allelic forms, while at the Est5 locus thee alleles were observed. Barley cultivars were divided into seven different groups, according to their specific allelic composition. Only in one case a single cultivar had a unique phenotype, as for the other, between 2 and 10 cultivars were present in each group.
