Abstract

'Double Shine', a cultivar of Gypsophila paniculata was newly developed for the cut flowers by Jeollabuk-do Agricultural Research & Extension Services. It has morphological characteristics of the spreading plant type, double florets of many petals and two pistils, emarginate petal tip and cup shaped calyx. Also 'Double Shine' has several traits such as strong flower stalk, bright colored flower, narrow branching angle and more or less resistance to powdery mildew and pest injury. Furthermore, 'Double Shine' produced higher primary branches, and longer flower stalk length with internodal length and than did a check variety 'Bristol Fairy' during summer cultivation in subalpine areas. Blooming of 'Double Shine' was delayed by 16 days, its floret had broader width, compared to 'Bristol Fairy'. Moreover, 'Double Shine' produced normal flowers with two pistils and 8.5 stamens, with little production of malformed flowers in the high temperature condition.

1999년 'Bristol Fairy' 유래의 결실되는 아조변이체인 'Gyp99' 계통을 선발하였고, 계통의 실생 중 선발을 거듭한 결과, 특성이 우수한 'Gyp08-63' 계통을 선발하여 2년간 특성검정을 통해 'Double Shine' 품종을 육성하였다. 'Double Shine' 품종의 초형은 개장형이고, 잎 모양은 둥근 피침형, 소화는 꽃잎수가 많고 암술이 2개인 밝은 백색 겹꽃으로 꽃잎은 주걱형, 꽃받침 모양은 컵형인 식물체 고유 특성을 가졌다. 또한 화경이 단단하고, 흰가루병과 충해에도 강한 편이다. 여름절화 작형에서 'Double Shine' 개화는 대조품종인 'Bristol Fairy'보다 16일 늦고 절간장과 화경장이 길었으며, 측지 분화가 많고 줄기가 굵고 분지각은 작았고, 기형화 발생이 없었다.
