Abstract

A new rose variety, was selected from the progenies of a cross between "Cosai" and "Tokimeky" in 2006 after evaluation trials for three years (2004-2006). "Waltz" was developed because of many petals and powdery mildew resistance. A standard type with large sized flower, "Waltz" shows in 11.0 cm flower diameter. "Waltz" produces 130 stems?m-2 in a year. It has red-white color flower and 49.6 petals per flower. The stem length of cut flower was long with 69.3 cm. Vase life of the variety could be as long as 9.6 days.

"왈츠"는 경기도농업기술원에서 2006년도에 육성한 절화용 장미 신품종이다. 이 품종은 2002년도에 진분홍색의 스탠다드 "Cosai"를 모본으로 하고 엽광택이 있는 분홍색의 스탠다드 "Tokimeky"를 부본으로 하여 교배를 하였다. 2003년에 실생을 양성하여 화색과 화형이 우수한 13계통을 예비선발하였으며 2004~2006년에 1, 2, 3차 특성검정과 품평회 결과 절화특성이 우수한 KR02-2-14계통(Gyeonggi R1-10)을 최종 선발하였다. 화색의 꽃잎 기부는 백색이며 가장자리 전체는 적색인 복색으로 매우 화려하다. 스탠다드 형태로 개화하고 화형은 반고심형이며 꽃잎수는 49.6매이고 향기 정도는 약한 편이다. 엽의 두께가 두껍고 광택이 있어 흰가루병에 강하다. 년간 절화수량은 130 본/$m^2$이고 절화장은 69.3 cm이며 줄기직경은 7.0 mm이고 엽수는 14.3매이며 절화중은 36.6 g이고 절화수명은 9.6일이다.
