Abstract

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.

장미 신품종 ‘To Dios’는 고양시농업기술센터에서 2013년에 종자친 ‘Vanilla perfume’과 화분친 ‘Marcia’간의 교배를 통하여 얻은 교잡 후대로부터 선발되었다. 꽃잎수가 48매인 스탠다드 오렌지 장미 ‘Vanilla perfume’을 종자친으로, 꽃잎수 96매의 스탠다드 흰색 장미 ‘Marcia’를 화분친으로 2009년에 교배하여 실생묘를 만들었다. 2010년부터 2013년까지 특성 검정한 결과 절화 특성의 우수성이 인정됨으로써 최종 선발하여 ‘To Dios’로 명명하였다. ‘To Dios’는 스탠다드 타입의 복숭아색(RHS Red Group 36B)을 띄며, 꽃 직경은 11.2cm으로 넓고, 128매의 꽃잎을 갖는다. 절화 수명은 15일이다. 개화소요일수는 47일이고, 연간 절화 수량은 160본/m²이다. ‘To Dios’는 국립종자원에서 2014년 3월 19일 품종보호등록(제 4875호) 되었다.
