Abstract

A new spray rose cultivar 'Glory Purple' was bred from the cross between a pink spray cultivar 'Macarena' and a pink spray cultivar 'Million Pink' at the National Institute of Horticulture & Herbal Science. The cross was made in 2004 and a candidate genotype which named as 'Glory Purple' was selected in 2009 after three years investigation for agronomical characters from 2007 to 2009. 'Glory Purple', a purple colored spray cultivar, has vigorous growth and has powdery mildew resistance. The major characteristics of this cultivar are high yield and long stem with relatively large flower size with $157stems/m^2/year$ in yield, 63.5 cm in mean length of cut flower, 6.8 cm in mean flower diameter, 25.78 in mean petal number, and 10.2 days in mean vase life. This cultivar is suitable for propagation by both cutting and grafting methods. The consumer's preference of this cultivar is relatively higher than that of the control cultivars, 'Pinky and Charming'.

2004년도에 화형이 우수하고 연핑크색의 스프레이 'Macarena' 품종을 모본으로 수량이 많은 핑크색 스프레이 'Million Pink' 품종을 부본으로 인공교배하여 2005년에 744개체의 실생묘를 획득하여 이들을 대상으로 2007-2009년까지 3차에 거쳐 특성을 검정한 후 최종 선발된 '원교 D1-143'을 'Glory Purple'이라고 명명하였다. 'Glory Purple'의 화색은 짙은 분홍색으로 RHS 칼라챠트번호 66B이다. 화형은 고심형이고 향기는 없다. 꽃잎수는 25.7개로써 'Pinky'와 같았고, 화폭은 5.9 cm로 'Pinky' 보다 작았다. 평방미터당 년간 절화수량은 157.1본으로 'Pinky' 보다 많았으며 절화장은 63.5 cm 절화경경은 6.3 mm로 'Pinky'와 비슷하였다. 또한 절화수명은 10.2일로 'Pinky' 보다 약간 길었으며, 흰가루병 저항성과 기호도 평가에서도 각각 'Charming'과 'Pinky' 보다 우수하였다.
