Abstract

A new spray chrysanthemum (Dendranthema grandiflorum) cultivar, 'Magic Yellow' was developed from a cross between 'Artist pink' and 'S03-47' by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2003 to 2008. Its characteristics were investigated three times from 2006 to 2008 under condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of 'Magic Yellow' was October 18th, and year-round production was possible by day length treatment. This cultivar has single-type flowers in good harmony with bi-color ray floret and green center. Its flower was 6.0 cm in diameter, and it had 11.4 flowers per stem in autumn. The days to flowering under the short day treatment is about 45 days in spring season, and 'Magic Yellow' showed the vase life of 22.9 days in autumn. This cultivar was registered for the protection in 2008.

'Magic Yellow' 품종은 경남농업기술원 화훼연구소에서 복색 홑꽃인 'Artist Pink'를 모본, 복색 홑꽃의 'SP03-47'을 부본으로 인공교배를 실시하여 2004에서 2008년에 걸쳐서 파종과 계통선발을 통해 육성하였다. 품종의 특성검정은 2006년부터 2008년까지 촉성재배와 억제재배, 자연재배 조건 아래서 3회에 걸쳐 조사하였다. 'Magic Yellow' 품종의 자연개화기는 10월18일경으로 빠른 편이며, 일장조절에 의해 주년재배가 가능하다. 초장이 120.2 cm로 크고 꽃 크기가 6.0 cm인 스프레이국화로 착화수는 11.4개이다. 화색은 황색과 적색을 가진 복색이며, 개화형태는 실린더형이다. 봄의 단일상태에서 'Magic Yellow' 품종의 개화소요일수는 45일 정도로 개화가 빠르며, 가을 절화수명 검정에서 22.9일로 긴 편이다.
