A new bicolored rose cultivar, 'Yellow Blue'.

摘要

A new bicolor standard rose (Rose hybrida [Rosa hybrida]) cultivar, Yellow Blue, was developed from a cross between the cultivars Berona and Deliason, followed by seedling and line selections in Korea Rebublic, in 1999. Characteristics were investigated from 2000 to 2004. This newly bred rose cultivar belonged to the Yellow group colour (RHS No. 9-C), has few thorns, high yielding and has standard large flowers. The ray floret and flower centre were harmonized as well and the vase life was approximately 11 days. This cultivar was registered as a commercial cultivar in 2003. It can be planted in any greenhouse production region in Korea..
