Abstract

A new spray rose cultivar "Morning Star" was bred from the cross between orange spray cultivar 'Macarena' and yellow spray cultivar 'Lion Sunshine' at the National Institute of Horticultural Research Institute. The cross was made in 2002 and "Morning Star" was finally selected in 2007 after investigating characteristics for three years from 2005 to 2007. "Morning Star", a orange spray cultivar grows vigorously and has good flower shape. The major characteristics of this cultivar are 170.2 stems/$m^2$/year in yield, 57.4cm in length of cut flower, 5.5cm in flower diameter, 48.5 in petal number, and 11.4 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer's preference of this cultivar is relatively higher than that of control cultivar, 'Sunny Lady'.

2002년도에 오렌지색의 스프레이 'Macarena' 품종을 모본으로 다화성인 황색의 스프레이 'Lion Sunshine' 품종을 부본으로 인공교배 하였다. 2003~2004년에 파종을 실시하여 517개체의 실생을 획득하여 이들을 대상으로 2005~2007년까지 3차에 거쳐 특성검정을 실시한 후 최종 특성검정 단계에서 기호도 조사를 실시한 결과 최종 선발된 '원교 D1-501' 을 "모닝스타" 로 명명하였다. "모닝스타"의 화색은 오렌지색으로 RHS 칼라챠트번호 29B이며 화형은 반고심형의 화형이며 향기는 '써니레이디'에 비하여 거의 없었다. 꽃잎수는 48.5개로서 '써니레이디' 의 52.9개보다 적었으며 화폭은 5.5 cm로 '써니레이디' 보다 약간 작았다. 평방미터당 년간 절화수량은 170.2본으로 '써니레이디'보다 많았으며 절화장은 57.4 cm 절화경경은 5.9 mm로 '써니레이디'보다 길이는 짧았지만 굵기는 굵어서 전반적으로 강건한 절화형태를 보였다. 소화수는 '써니레이디'의 3.9개보다 많은 4.9개를 보여 우수한 스프레이 형태를 지닌 절화장미로 평가되었으며 절화수명은 11.4일로 '써니레이디' 보다 약간 짧았다.
