A new standard rose cultivar ‘Big Bang’ was bred from the cross between Yellow standard cultivar ‘Landora’ and Yellow standard cultivar ’Birdy’ at the National Institute of Horticulture & Herbal Science. The cross was made in 2005 and ‘Big Bang’ was finally selected in 2011 after investigating characteristics for three years from 2009 to 2011. ‘Big Bang’, a red standard cultivar grows vigorously and has Crown Gall Resistnat. The major characteristics of this cultivar are 119.8 stems/㎡/year in yield, 99.0±12.6 cm in length of cut flower, 13.5±0.3 cm in flower diameter, 40.0±3.2 in petal number, and 9.0±0.4 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, ‘Vital’.
