Abstract

Cymbidium (C.) spp. 'Wedding Day' was developed by the National Institute of Horticultural and Herbal Science, Rural Development Administration in 2021. This cultivar was derived from the artificial cross between C. 'Boksam Holiday' and C. 'Persicolor' in 2008. After the crossing, 112 seedlings were obtained through in vitro germination and transferred to the green house. Based on their vegetative and flowering characteristics, two lines were selected through the first selection. To confirm the stability and uniformity of the two lines, the first and second trials were conducted from 2017 to 2021. As a result, the final line with the code 'C0844-29' was selected as 'Wongyuo F1-78'. After evaluating consumer preference, the line was named as 'Wedding Day'. This hybrid is medium sized cultivar with long vase life of cut flowers and more than 11 white flowers per stalk. It has 63.2 cm of erect stalks which are suitable for cut flower. The leaves are 65.8 cm long and located lower than the flowers, providing appropriate shape for viewing the flowers. It starts flowering from late January. It has sufficient proliferation ability to enable mass proliferation for commercial use (Registration No. 9523).

심비디움 '웨딩데이'는 국립원예특작과학원에서 2021에 육성한 신품종으로 2008년에 C. spp. 'Boksam Holiday'와 C. spp. 'Persicolor'를 인공교배를 통해 개발하였다. 교배 후 기내 파종을 통해 112개의 실생 개체를 배양하여 온실로 순화하였다. 이후 생육 및 개화 특성 평가를 통해 2 계통을 1차 선발하였다. 2선발 계통의 안정성과 균일성을 확인하기 위하여 2017년부터 2021년까지 1, 2차 특성검정을 진행하였다. 그 결과 최종적으로 'C0844-29' 1 계통을 선발하였고, '원교 F1-78'로 계통명을 부여하였다. 이후 육성계통 평가회를 통해 기호성을 인정받았고 '웨딩데이'로 명명하였다. '웨딩데이'(품종보호 등록번호: 제9523호)는 절화수명이 길고 백색의 소화가 11개 이상 달리는 다화성 중형종이다. 꽃대가 직립하고 63.2 cm로 길어 절화로 이용하기에 적합하다. 잎 길이는 65.8 cm로 꽃 높이보다 낮아 꽃을 가리지 않고 감상할 수 있다. 1월 말부터 개화하는 중만생종이며, 기내에서 배양 시 증식함에 있어 문제가 없어 상업적 활용이 가능할 것으로 보인다.
