Molecular and genetic analysis of potato cultivars from the collection of VSC RAS for resistance to phytopathogens

Growing potatoes in the traditional way is a long and difficult process. The use of DNA markers, which are closely related to genes for resistance diseases pests, significantly enhances search breeding valuable samples expands horizons sample tested material and, thus, reduces time required create new potato varieties. With help you can select offspring with certain combinations genes. This especially important if control same trait, example, particular pathogen. allows creation genotypes high phytopathogens. As result molecular screening samples, it was revealed that PVX marker gene virus X (Rx) diagnosed 7 studied samples. Ry186 Rychc not found among sample. Markers RYSC33, YES3-¬3A linked Ryadg Rysto were 2 A aureus cyst nematode (H1) pale (Gpa2) five genotypes.
