Abstract: The allelic composition of the three loci controlling HMW glutenin subu-nitsof a total of 2064 varieties from the "old"wheat collections was studies,and the comparison of the present results to those of the other studies was carried out. As the wheat varieties had been improving, the frequences of Glu-Alb, Glu-Blb, e and Glu-Dla decreased, the frequences of Glu-Ala, Glu-Bla,c,d and Glu-Dld increased, no change occurred for the other alleles in frequence. Glu-Ala, Glu-Bli and Glu-Dld assessed as being good contributors to bread-making quality were in higher frequence in Australian cultivars than the "oid" wheat collection, showed that those three alleles contributed to good breed-making quality of Australian wheat. More attention should be paid to the Glu-Blb in the future research and breeding programs.
