STRAWBERRY RESISTANCE TO THE MAJOR FUNGAL PHYTOPATHOGENS: R-GENES AND THEIR DNA MARKERS

The garden strawberry Fragaria × ananassa (Duchesne ex Weston) Duchesne ex Rozier (1785) is a perennial herbaceous plant of the Rosaceae family; it is cultivated all around the world. It accounts for more than half of the global volume of berries production. In Russia, more than 160 tons of garden strawberries are grown annually, but according to Russian scientists, this crop has a much higher productivity potential. Various pathogens, including bacterial, viral and fungal infections, negatively affect the productivity of strawberry. Anthracnose (caused by Colletotrichum Corda . ), crown rot ( Phytophthora cactorum Lebert & Cohn), red core disease ( Phytophthora fragariae var. fragariae Hickman), fusarium wilt ( Fusarium oxysporum  f. sр. fragariae Winks & Williams ) and strawberry powdery mildew ( Podosphaera aphanis [ Sphaerotheca macularis ] (Wallr.) U. Braun & S. Takam) are among the most important fungal diseases of strawberry. This review discusses the current data about the known genes and quantitative trait loci (QTLs) associated with resistance to listed plant pathogens. The review also offers information about molecular markers of different types: SDRF, AFLP, SSR, SCAR, SNP, associated with these genes/QTLs and used in the molecular screening of strawberry collections for practical purposes.
