Modern methods of genomic analysis in investigations of quantitative determinants in plants (review)

On the basis of literature data the authors consider the modern principles of identification and mapping of loci of quantitative determinants (QTL) in plants. The short description of the most prevalence classes of genetic markers on the LNA level and their usage for genetic mapping were presented. The strategy of QTL mapping and gene cloning which are determined the quantitative economically valuable determinants in plants were considered. The ways of further usage of molecular-genetic methods in practice genetics and plants breeding were discussed.
