Therefore breeding studies play an important role for development of new cultivars resistant against fungal diseases. The aim of this research was to develop new F<sub>1</sub> population and evaluate the resistance of hybrids to powdery and downy mildew via marker assisted selection (MAS). Resistant ‘Regent’ and susceptible ‘Boğazkere’ varieties were used to obtain hybrid population. A total of 6 markers belonging to 3 genomic regions were used for DNA based selection. Four SSR (UDV15, VMCNG2f12, VMC7F2 and UDV305) and two SCAR (ScORNA7-760 and ScORN3-R) markers which were developed to the resistance loci of Rpv3 and Ren3 were used for DNA based selection. The results were evaluated together with powdery mildew inoculation observations. When inoculation observations and MAS were evaluated, genotypes resistant, tolerant and susceptible to powdery and downy mildew were identified. Especially 16 genotypes identified as resistant to powdery mildew, can be used in future breeding programs.</p> ER -
