Abstract
A new standard rose cultivar "Snow Day" was bred from the cross between pink standard cultivar "Saphia" and pink standard cultivar "Bridal Beauty" at the National Institute of Horticulture & Herbal Science. The cross was made in 2003 and "Snow Day" was finally selected in 2008 after evaluating characteristics for three years from 2006 to 2008. A white standard cultivar, "Snow Day" grows vigorously and resistant to powder mildew. The major characteristics of this cultivar are $152stems/m^2/year$ in yield, 81.8 cm in length of cut flower, 11.3 cm in flower diameter, 29.2 in petal number, and 13.7 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer's preference for this cultivar is relatively higher than that for the control cultivar, "Tineke".
