Abstract

A new spray chrysanthemum (Dendranthema grandiflorum) cultivar "Green Witch" was developed from a cross between 'S04161' and 'S04109' by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2004 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 "Green Witch" was October 19th, and year-round production was possible by day length treatment. Its capitulum was 3.2cm in diameter, and had 15.9 head per stem in autumn. Its ray floret was green central zone. To flower in the short day condition, for "Green Witch" was about 44 days in spring, and "Green Witch" showed the vase life of 25.3 days in autumn. This cultivar was registered for a commercialization in 2008.

"Green Witch" 품종은 경남농업기술원 화훼연구소에서 녹색 폼폰형인 'SL04-161'을 모본, 분홍색 폼폰형인 'SL04-109'를 부본으로 인공교배를 실시하여 2004에서 2008년에 걸쳐서 파종과 계통선발을 통해 육성하였다. 품종의 특성검정은 2006년부터 2008년까지 봄 촉성재배와 가을 억제재배 조건 아래서 3회에 걸쳐 조사하였다. "Green Witch" 품종의 자연 개화기는 10월19일경으로 개화가 빠르며, 일장조절에 의해 주년재배가 가능하다. 초장이 93.1 cm이고 꽃 크기가 3.2 cm인 산티니계의 스프레이국화로 착화수는 15.9개로 비교적 많은 편이다. 화색은 녹색이며, 개화형태는 실린더형이다. 봄의 단일상태에서 "Green Witch" 품종의 개화소요일수는 44일 정도이며, 가을 절화수명검정에서 25.3일로 아주 긴 편이다.
