PCR-analysis with primers to Wx-loci of T. aestivum L. genome lets us run the controlled selection of genotypes with null-alleles of Wx-genes while creating bread wheat lines with amylopectin type of starch. Microsatellite analysis of selected individual plants which were the carries of three null-alleles of Wx-genes (Wx-A1b, Wx-B1b, Wx-D1b) and the cluster analysis in the complex allowed us to pick out four genotypes, which were very close related genetically to the parent form variety Kuyalnik.

Key words: amylose, starch of amylopectin type, microsatellite, Wx-genes
