Abstract

A new standard rose cultivar ‘White Jwelry’ was bred from the cross between purple standard cultivar ‘Saphir’ and purple standard cultivar ‘Noblesse’ at the Jeollanamdo Agricultural Research and Extention Services (JARES). The cross was made in 2007 and seedlings were produced. After the evaluation of specific characters from 2009 to 2011, it was finally selected and named as “'White Jwelry” that has standard flower type with white color (RHS Color Chart White Group 155C). The major characteristics of this cultivar were as follows: this cultivar produced 143.6 stems/m 2 /year, and it showed 66.4cm in length of cut flower, 10.4 cm in flower diameter, 45.6 in petal number, and 10.3 days in vase life. This cultivar can be propagated by both cutting and grafting. Tthe consumer’s preference of this cultivar is relatively higher than that of control cultivar, ‘Rose Yumi’.
