Abstract

A new bright yellow gerbera (Gerbera hybrida Hort .) cultivar, ‘Joyful’, was released by the Flower Research Institute of Gyeongsangnam-do Agricultural Research & Extension Service in 2013. ‘Joyful’ was developed in Changwon from 2005 to 2006 and is a cross between ‘Chowoo’, a semidouble type gerbera cultivar with yellow-orange colored flowers, and ‘Focus’, a semi-double type cultivar with yellow colored flowers. The characteristics trials for selection were conducted from 2007 to 2009. ‘Joyful’ has large, semi-double type flowers with yellow (RHS, 12-A) ray florets and a brown central part. It also has a stable flower shape, strong peduncles, and a vase life of 12.8 days. The average flower yield of ‘Joyful’ was determined in greenhouse trials carried out from 2008 to 2010 and is 49.2 stems per plant per year. ‘Joyful’ was demonstrated to be a new cultivar based on ploidy tests and RAPD analysis and was registered (Grant No. 4574) to the Korea Seed and Variety Service (KSVS) for commercialization in 2013.

경남농업기술원 화훼연구소에서 ‘포커스(Focus)’와 ‘초우(Chowoo)’ 품종 간의 교배 후, 특성검정을 통해 선명한 황색의 반 겹꽃 절화용 거베라(Gerbera hybrida Hort.) ‘조이풀(Joyful)’을 육성하였다. 인공교배로부터 얻은 실생계통을 2005년부터 2010 년까지 조직배양과 포장재배를 통해 개체 증식과 생육 및 개화특성 검정, 농가 실증, 절화수명 등을 평가하였다. ‘조이풀’의 화색은 황색(12-A)으로 꽃의 직경이 12.8cm의 대륜화이며, 화경장은 60cm로 길었다. 개화 소요일수가 89일 정도이며, 절화 수량도 49.2개로 대조품종보다 개화가 빠르고 수량도 많았다. 절화수명에 있어서도 12.8일로 비교 품종보다 우수하였으며, 절화 보존 시 꽃크기 변화 등이 적고, 외형 등의 변화가 대조품종보다 우월하여 절화로서 높은 관상가치를 보였다. 또한 농가 실증이나 기호도 평가 시 잘 조화된 절화품종으로 평가받았다. RAPD 분석에서 육성 품종이 모본과 부본의 밴드 패턴이 교 배품종인 ‘조이풀’에는 모두 나타나서, 양친간 교배에 의해 육성된 품종임을 확인할 수 있었다. ‘조이풀’은 2013년에 신품종 으로 품종보호등록(품종보호 제4574호)이 되었으며, 절화용 거베라로서 농가소득 창출에 기여할 수 있을 것으로 기대된다.
