- Abstract
- A new spray chrysanthemum (Dendranthema grandiflorum Ramat.) 'Green Joy' was developed from a cross between 'Rocky' and 'Biarritz' by selections of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services from 2003 to 2007. Its characteristics were investigated three times from 2005 to 2007 under the condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of 'Green Joy' was October 27th, and year-round production was possible by day length treatment. Its capitulum was 4.3 cm in diameter, and had 225.6 ray florets and 16.6 head per stern in autumn. Its ray floret was green color. Days to flowering under the short day treatment is about 42 in spring, and the vase life was 21.5 days in autumn. This cultivar was registered for a commercialization in 2008.
