PROSPECTS OF USING DNA-MARKERS IN GRAPEVINE BREEDING [PDF]

Russian Vine, 2021
DNA-markers are actively used for the fin-gerprinting of genotypes, identification of va-rieties, in phylogenetic studies, for assessing genetic diversity, for mapping genes, etc. The article presents an analytical review of the achievements in the use of molecular markers in grape genetics as a basis for breeding works.
