Abstract

'Dream Pink', a cultivar of Gypsophila paniculata was newly developed for cut flowers by Jeollabuk-do Agricultural Research & Extension Services. It has morphological characteristics of the intermediate plant type, double florets with many petal and two pistils, emarginate petal tip and campanulate calyx shape. Also 'Dream Pink' had several other traits such as strong flower stalk, deep pink flower color, resistance to powdery mildew and pest injury. Furthermore, 'Dream Pink' produced higher number of nodes, primary branches, longer flower stalk length with long intermodal length. In subalpine area, 'Dream Pink' cultivar showed narrow branching angle as compare to 'My Pink', during the summer cultivation. Blooming in 'Dream Pink' was delayed by 5 days, its florets were broader with more number of petals as compare to 'My Pink'.

1999년 'Bristol Fairy' 유래의 결실되는 아조변이체 Gyp99 계통을 선발하였고, 그 계통의 실생 중 계통선발을 거듭한 결과 특성이 우수한 Gyp06-29 계통을 선발하여 2년간 특성 검정을 통해 'Dream Pink'를 육성하였다. 'Dream Pink' 품종은 중간형의 초형을 가지고, 소화는 꽃잎수가 많고 암술이 2개인 분홍 겹꽃이며, 꽃잎은 도란형, 꽃받침 모양은 종형인 식물체 고유특성을 갖는다. 또한 화경이 강하고 흰가루병에 매우 강하고 충해에도 강한 편이다. 여름절화 작형에서 'Dream Pink' 개화는 대조품종인 'My Pink'보다 5일 늦고 절간장과 화경장이 길었으며, 마디와 측지 분화가 많고 분지각은 작았다. 소화와 꽃받침 크기가 크고 꽃잎수가 많았다.
