‘Big Bang’ 품종은 꽃이 크고 생육이 왕성하며 엽소 및 잎 마름병에 강한 백합 신품종을 육성하기 위하여 2010년 충남농 업기술원 태안백합시험장에서 교배한 OT(Oriental hybrid × Trumpet hybrid) 백합의 종간교잡종이다. 모본으로는 노랑색의 OT백합 ‘Biarits’ 품종을, 부본으로는 백색의 오리엔탈백합 ‘O11-149’ 계통을 화주절단수분법에 의해 교배한 후 2010년부터 2013년까지 기내 종자배양 및 증식 육묘하여 2014년 우수 계통(OT14-6)을 1차 선발하였다. 2016년부터 2018년도에 걸쳐 ‘Nymph’ 품종을 대조품종으로 하여 일반재배를 통한 특성 검정을 실시하였으며, 2016년 화훼연구소 백합 육성계통 평가 회에서 우수계통으로 선발되어 ‘Big Bang’로 명명한 후 충청 남도와 농촌진흥청 농작물직무육성 신품종선정위원회 심의를 거쳐 국립종자원에 품종보호출원 하였다. ‘Big Bang’ 품종의 자연개화는 중부지역에서 6월 16일로 ‘Nymph’ 품종과 비슷하였고 초장은 155.3cm이었다. 적색 반점에 복색(백색+적색)의 화색과 사발화형의 꽃모양을 나타내었다. 재배에 있어서는 진딧물과 잎마름병 등의 병해충 방제를 주기적으로 실시하고, 영양분 관리 등 일반적인 재배관리를 통해 안정적인 구근생산 및 고품질 절화가 가능하다.
A newly developed Oriental × Trumpet (OT) intersectional hybrid lily cultivar entitled ‘Big Bang’ possessing high growth rates and strong levels of resistance to leaf burn and Botrytis was created at the Flower Research Institute of Chungcheongnam-do Agricultural Research and Extension Services in the calendar year 2018. In the year 2010, the yellow-flowered female parent Lilium OT hybrid ‘Biarits’ was crossed with the white-flowered male parent L. Oriental hybrid ‘O11-149’ utilizing a cut style pollination method (CSM) for breeding purposes. Adaptation trials were carried out upon the candidate line in order to develop various characteristics via seed culture in vitro, multiplication, and seedlings from 2011 to 2013. The first selection was chosen in 2014, and the line was tentatively dubbed ‘OT14-6’. The present study compared the flowering characteristics, bulb production, external shape type, and growth with those of ‘Nymph’ from the calendar years 2016 to 2018. Consumer pref erence f or the evaluated characteristics was surveyed over the course of a l ily flower show that took place at the Flower Research Institute in the year 2016, and a second selection, dubbed ‘Chungnam OT-7’, was chosen according to results from the show. The chosen line was registered as the OT hybrid ‘Big Bang’ in the year 2018. The natural flowering time of ‘Big Bang’ initiated during June 16th, which was akin to ‘Nymph’ at the central district. The plant height of ‘Big Bang’ measured 155.3 cm, the flowers were a double color (white-red) of red spots, and of the upward blooming type. Bulbs required careful employment of general cultivation techniques, including controlling diseases and insects, alongside nutrient and moisture management.
