A standard rose cultivar, ‘To Dios’(Rosa hybrida) was selected for use as a cut flower from the progeny of a cross between ‘Vanilla perfume’ and ‘Marcia’ at the research and development division of the Goyang-si Agricultural Technology Center in 2013. ‘Vanilla perfume’, an orange-colored (RHS Orange Group 27C) standard rose cultivar with 48 petals, was used as the female plant. ‘Marcia’, a white-colored (RHS Green white Group 157B) standard rose cultivar with 96 petals was used as the male parent. A cross was made in 2009 and seedlings were produced. Selections were made between 2010 and 2013, and a plant with good cut flower traits was finally selected and named ‘To Dios’. ‘To Dios’ is a standard rose with large flowers of 11.2 cm in diameter and 128 peach-colored (RHS Red Group 36B) petals per flower. Vase life of this cultivar is up to 15 days. It takes 47 days from pruning to blooming and cut flower productivity is approximately 160 stems/m2 per year. ‘To Dios’ was registered as a new cultivar No. 4875 with the Korea Seed & Variety Service on March 19, 2014.
