The Effects of the Polinator Grape Cultivar Kalecik Karasi on the Progeny Fertility of Some Grape Cultivars

In this research, germination rate of seeds and fruit set of F1 hybrids obtained by hybridization studies conducted on Italia, Muscat Hamburg, Papaz karasi, Narince and Riesling grape cultivars were pollinated with Kalecik karasi grape cultivar, was investigated. Among cultivars which were pollunated with Kalecik karasi grape cultivar, the highest fruit set ratio was obtained from Muscat Hamburg grape cultivar (38.0%) however the lowest fruit set ratio, was obtained from Riesling grape cultivar (18.0%). The highest germination rates of seeds achieved from Italia grape cultivar (43.3%). The lowest germination rates of seeds achieved from Papaz karasi (17.0%) cultivar. When seedling set ratios investigated among F, off springs that were obtained by hybridization studies, the highest seedling set ratios were obtained from Riesling (85.0%). However Ata sarisi grape cultivar had the lowest seedling set ratio (50.1%). Approximately, 232 F1 hybrid progenies were producted as a result of hybridizations.
