Study Of Genetic Diversity And Resistance Of Fruit Crops To Main Pathogens Using DNA Markers

Breeding modern varieties of fruit crops requires the study of their biodiversity as a source of genes for useful traits, with the aim of transferring them to genome of commercial varieties. Application of genomic technologies can significantly speed up the breeding process. Identification and application of DNA markers for the study of genetic diversity, varietal identification, as well as the transfer of genes of valuable economic traits through marker assisted selection programs is of great applied importance. The article discusses the results of studies to identify genes and DNA markers associated with resistance of some fruit crops to major diseases.
