Abstract

The white flowered 'Eorayeon 2ho' is a cultivar of Lilium ${\times}$ formolonga developed in Department of Horticultural Sciences, Kangwon National University, Chuncheon, Korea. $F_1$ hybrid LA-77 was selected from the cross between a selected selting line($S_3$) of L. longiflorum 'Lorina' and a selfing line($S_3$) of L. ${\times}$ formolonga 'Augusta' in 2000. The $F_1$ hybrid LA-77 was backcrossed by a selected line of L. ${\times}$ far molonga 'Raizan No. 1' from 2001 to 2002. 'MF-No.2' was preliminarily selected for its upward flowering habit and high plant height. The evaluation of characteristics was investigated from 2003 to 2004 in Chuncheon and Yungweol, Kangwon province. 'Eorayeon 2ho' blooms in early July at outside, with high resistance to Botrytis and showing upward flowering habit. The plant height is 132.6 cm and the percentage of seed germination is 95.3%. Mean tepal length and width are 16.0 em and 4.3 cm, respectively. The length and width of leaf is 12.3 and 3.2 cm, respectively. This seed propagating cultivar shows high plant height suitable for a cut flower.

'어라연 2호'는 강원대학교에서 2003년에 육성된 절화용 신나팔나리 품종이다. 2000년에 육종목표에 따라 나팔나리 'Lorina' 자식계통을 모본으로 신나팔나리 'Augusta' 자식 계통을 부본으로 교잡을 실시하였다. 2001년에는 개화기에 초세가 강건하고 꽃이 크며 엽형이 좋은 'LA-77'계통을 모본으로 선발하고 조생종이며 꽃 모양이 좋고 개화방향이 상향인 'Raizan No.1' 자식 계통을 2회 연속 교잡을 실시하였다. 2003년에 각종 형질이 우수한 'MF-No.2'계통을 선발하고 이 계통을 대상으로 2003년부터 2년간 농촌진흥청 농사시험연구조사기준에 따라 특성검정 및 계통 평가회의 기호성 조사를 통해 최종적으로 절화용 신나팔나리 신품종으로 선발하여 '어라연 2호'라 명명하였다. '어라연 2호' 품종의 발아율은 95.3 %이고, 개화소요일수는 194.2일이며, 포장과 수송이 편리한 상향개화성이다. 만개시 화경은 13.4 cm이고, 외화피장은 16.0cm이고, 외화피폭은 4.3 cm이다. 개화수는 3.1개이며, 초장은 132.6 cm이다. 잎마름병에 대한 저항성이 강하고, 절화율이 100%에 달한다. '어라연 2호'는 '어라연 1호'보다 초장이 20cm 이상 길어 수출용으로 적합한 품종이다.
