Marker Based Screening of F1 (Rosalie x Fuji) Mapping Population for Major Scab Resistance Gene Rvi6 in Apple (Malus × Domestica)

Apple (Malus domestica Borkh.) being the most significant and profitable crop cultivated in temperate areas is extremely susceptible to apple scab disease. It becomes problematic when pathogens develop resistance farmers spend a lot of money on fungicides. These widespread worries reasonably call for different disease management strategy order use fungicides less frequently. As result, current study focused gene introgression cultivar ‘Fuji’ using phenotypic marker-assisted screening hybrids created by crossing succeptible with resistant ‘Rosalie’. There was 1:1 Mendelian segregation ratio between hybrids. From our study, obtained have potential be utilized as commercial varieties after evaluation important pomological traits also sources downstream breeding programs.
