The superior line of ‘0013-9’ was selected in Daegwallyeong from 2001 to 2003 year, and growth and flower characterization were conducted from 2004 to 2007 year in field of Daegwallyeong and Jinbu of Pyeongchang, Gangwon-do, Namwon, Jeollabuk-do and Jeju Special Self-Governing-do. The flower showed violet blue (VB 96A) color at opening, the petal of flower have not spot and flower stem color was purple. Flowers was opening at the same time from bottom to upside. Plant height was 68.1 cm, and number of flower stems per plant was 5.3 ea., number of flower node per stem is 5.9 ea., and Number of flowers per stem was 32.2 ea.. The flowering of ‘Skyhope’ cultivar was bloomed from the middle of July in Daegwallyeong and the later of July in Jinbu, Pyeongchang, Kangwon-do and the early of July in Namwon, Jeollabuk-do and the later of July in Jeju Special Self-Governing-do. ‘Skyhope’ cultivar can be used for cut flower.

A new Gentiana spp. cultivar “Skyblueball” was bred by crossing between “Jinbu-65 line” with violet blue (VB 95B) colored petals as female and “Jinbu-1 line” with violet blue (VB 93B) petals as male in 2000 year. The superior line of 00-168-3 was selected in Daegwallyeong from 2001 to 2003 year, and its growth and flower characterization were conducted from 2004 to 2007 year in field of Daegwallyeong and Jinbu, Pyeongchang, Gangwon-do, Namwon, Jeollabuk-do and Jeju Special Self-Governing-do. The flower showed violet blue (VB 96C) color at opening, the petal of flower had not spot and flower stem color was purple. The flowers were bloomed at the same time from bottom to upside (Table 1). Plant height was 62.9 ㎝ , number of flower stem per plant is 8.3, number of flower node per stem was 5.3, and number of flower per stem was 21.7 (Table 2).

절화의 관상기간 중 꽃잎의 탈색 완화에 적합한 조건을 알아보기 위하여 리시안서스, 용담, 국화, 공작초를 대상으로 광도(500, 5,000, 10,000lux)와 자당 처리를 실시하였다. 광도의 차이와 자당의 유무의 차이를 비교해 볼 때 리시안서스와 용담은 각각 자당이 처리된 5,000lux에서 10.9일 10,000lux 역시 10.9일로 관상기관이 길게 나왔다. 반면 국화는 500lux에서 10.5일로 관상기관이 길게 나왔다. 공작초는 광도와 상관없이 대조구에서 10.2일로 관상기간이 길었다. 꽃잎의 탈색완화 효과는 가장 높은 광도 하의 꽃잎 색이 진하게 나왔고, 대조구 보다는 자당이 첨가된 처리구에서 진하게 나오는것을 알 수 있었다. 이상의 결과로부터 고광도의 조건과 자당의 첨가는 안토시아닌의 합성을 증가시키기 때문에, 꽃잎탈색을 지연시키는 것으로 나타났다.
