Abstract

A new bright-pink gerbera (Gerbera hybrida Hort.) cultivar, ‘Pink Garden’, was released by the Flower Research Institute of Gyeongsangnam-do Agricultural Research & Extension Service in 2013. ‘Pink Garden’ was developed in Changwon on 2007 and is a cross between ‘Pink Light’, a semi-double-type gerbera cultivar with pink flowers, and ‘Mephysto’, a semi-double-type cultivar with purple flowers. The characteristic trials for selection were conducted on 2008. ‘Pink Garden’ has large, double-type flowers with pink (RHS, 55B) ray florets. It also has a steady flower shape, middle-strong peduncles, and a vase life of 13.5 days. The average flower yield of ‘Pink Garden’ was determined in greenhouse trials conducted from 2009 to 2010 and was determined to be 49.5 stems per plant per year. ‘Pink Garden’ was revealed to be a new cultivar based on random amplified polymorphic DNA analysis and was registered (Grant No. 4575) in the Korea Seed and Variety Service for commercialization in 2013.

경남농업기술원 화훼연구소에서 핑크색 대륜계의 ‘핑크라이트’를 모본으로 하고 핑크색 대륜계의 ‘메피스토’를 부본으로 인공교배를 실시하여, 선명한 핑크색의 겹꽃으로 절화용 거베라 ‘핑크가든(Pink Garden)’을 육성하였다. 인공교배에서 획득한 실생 계통으로부터 선발하여 조직배양과 재배를 통해 개체 증식과 생육 및 특성 검정, 농가 실증, 절화수명 등을 평가하였다. ‘핑크가든’의 화색은 선명한 핑크색(RHS 55B)으로 꽃의 직경이 11.5cm 정도의 대륜화이며, 화경장은 58.3cm 정도였다. 개화소요일수가 89.6일 정도이며, 절화 수량도 49.5개로 대조품종보다 개화가 빠르고 수량도 많았다. 절화수명에 있어서도 13.5일로 대조품종보다 우수하였으며, 절화보존 시 꽃 크기 변화 등이 적고, 외형 등의 변화가 대조품종보다 우월하여 절화로서 높은 관상가치를 보였다. 또한 농가 실증이나 기호도 평가 시 잘 조화된 절화 품종으로 평가 받았다. RAPD 분석에서 육성품종이 모본과 부본의 밴드 패턴이 ‘핑크가든’에 모두 나타나, 양친 간 교배에 의해 육성된 품종임을 확인할 수 있었다. ‘핑크가든(Pink Garden)’은 2013년에 신품종으로 품종보호등록(품종보호 제4575호)이 되었으며, 절화용 거베라로서 농가소득 창출에 기여할 수 있을 것으로 기대된다.
