[The effectiveness of selection for the DNA markers of quantitative trait loci in maize populations].

DNA-markers of some agronomically valuable quantitative trait loci were detected by SSR- and ISSR-PCR. 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 (gamma K26 x Mo17) 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.
