The effectiveness of selection for DNA-markers of quantitative trait loci in maize populations

DNA-markers of sоme agronomically valuable quantitative trait loci were detected by SSR- and ISSR-РCR. Method of genetic improvement of initial population for polygenic trait complex is proposed basing on direct selection of plants according to their genotype marker profiles. Experimental modelling of marker selection within populations (ГК26 х Мо17) F₃-F₄ has been carried out. Requirements of marker combination in test systems and criteria of marker informativity have been grounded. Significant effectiveness of marker selection in comparison with traditional methods of selection in maize breeding has been demonstrated.
