Abstract

'Happy Dream' a cultivar of Gypsophila paniculata, was newly developed for cut flowers by Jeollabuk-do Agricultural Research and Extension Services in 2010. This hybrid was selected from 39 seedling gathered from an open pollination of 'Gyp06-31'. It has morphological characteristics of a intermediate plant type, lanceolate leaf shape, double florets of many white petals with spatulate shape, truncate petal tip, and cup shaped calyx. 'Happy Dream' also has several traits such as strong flower stalk, narrow branching angle, and more or less resistance to powdery mildew and insect injury. Furthermore it has longer flower stalk and internodes than a check cultivar 'Bristol Fairy' during summer cultivations in the subalpine area. Blooming of 'Happy Dream' is 23 days later, its floret is much broader in width, and leaves are shorter but broader as compared to 'Bristol Fairy'.

'Bristol Fairy' 아조변이체 'Gyp99'의 한 계통인 'Gyp06-31'의 방임수분 결과 얻어진 실생계통으로부터 특성이 우수한 'Gyp08-42' 계통을 선발하여 2년 동안 특성평가 및 특성검정을 통해 'Happy Dream' 품종을 육성하였다. 'Happy Dream' 품종의 초형은 중간형이고, 잎 모양은 피침형, 소화는 주걱형의 꽃잎수가 많은 백색 겹꽃으로 꽃잎 끝 모양은 약간 둥근형 그리고 꽃받침 모양은 컵형인 식물체 고유 특성을 가졌다. 또한 화경이 단단하고 분지각이 작으며, 흰가루병에 강하고 충해에도 강한 편이었다. 여름절화 작형에서 'Happy Dream' 개화는 'Bristol Fairy'보다 26일 늦고 절간장과 화경장이 길고 줄기가 굵었다. 'Happy Dream'의 엽장은 'Bristol Fairy'보다 짧았으나, 엽폭은 넓고 소화는 더 컸다.
