To increase the effectiveness of fruit resistance breeding application of the Marker Assisted Selection ( MAS) is advantageous. For generating molecular markers which enable the following of interesting traits basically two methods are available: targeted marker design based on conservative region of already known Resistance ( R) gene sequences or randomly generated markers. The creation  and the application  of  these homology  based  markers  are the object of this review in  the main  temperate zone  fruit species.application/pdfResistance Gene Analoge (RGA),Marker Assisted Selection ( MAS}fruit breedingfunctional markerfolyóiratcikkOpen Accesshttps://doi.org/10.31421/IJHS/15/1-2/806International Journal of Horticultural Science1-215Int. j. hortic. sci.2676-931X
