Özet
Roses are highly demanded ornamental plants widely cultivated as pot miniature roses, cut roses, and old garden roses. Given their popularity and economic importance, it is crucial to investigate the effects of hybridizing different forms on seed yield and quality to assess the success of such combinations in the development of new commercial rose varieties. This study investigated the effects of cross combinations between pot miniatures and garden/cut roses on seed yield and quality. Rosa White Star, a miniature rose, was used as the seed parent, while three garden roses (Spelwark, Gräfin Diana, and Genotype 1) and two cut rose varieties (Magnum and Tineke) served as pollen parents. Parameters observed included; fruit set, number of seeds per fruit, fruit weight, seed weight, and seed germination rate. The highest number of seeds per fruit was observed in ‘Rosa White Star’ × ‘Tineke’ (14.0), whereas the lowest was observed in ‘Rosa White Star’ × ‘Genotype 1.’ The highest germination rate was 15.31% in ‘Rosa White Star’ × ‘Tineke,’ while seeds of ‘Rosa White Star’ × ‘Genotype 1’ did not germinate. The findings indicate that hybrids between miniature roses and certain cut roses may be more productive than garden roses. Among the combinations tested, the cut rose variety Tineke showed the highest compatibility as a pollen parent with Rosa White Star. To improve seed yield and quality in miniature roses, future breeding efforts should prioritize the identification of genetically compatible parental combinations and the development of optimized hybridization strategies. Such an approach is expected to enhance the efficiency of breeding programs and support the development of high-value commercial rose varieties.
