Abstract:

Hybridization breeding is the most widely used method in the development of rose varieties in the world. Recently, with the increasing consumer demand for fragrance in cut flowers, the breeders has led to improve the scented rose in breeding. by Rosa Damascena Mill. known as oil rose, is one of the most important fragrant rose species in the world. Parental selection is one of the factors affecting success in the development of new rose varieties by hybridization breeding. The study was conducted on 01 May-30 October 2019 to determine the performance of Rosa damascena as a male parent in rose breeding through hybridization. In this study, the viability and germination rate of the flower were examined in Rosa damascena, while the number of fruit and seeds and the germination rates of hybrid seeds were determined in 10 hybrid combinations. The maximum number of seeds per fruit was determined in Freedom x Rosa damascena combination with 31.5 seeds, followed by Pink Akito x Rosa damascena combination with 26.6 seeds while the minimum number of seed per fruit was 7.29 with Cherry Brandy x Rosa damascena combination. The highest germination rate (32.33%) was determined in Pink Akito x Rosa damascena when the lowest germination rate was examined in Black Magic x Rosa damascena combination.
