고온기 생육 및 개화특성이 우수한 절화용 스프레이 국화 ‘Perky Star' = A Spray Chrysanthemum Cultivar for Cut Flower, ‘ Perky Star ’ , with Excellent Growth and Flowering Characteristics at High Temperature Period

국문 초록 (Abstract)

경기도농업기술원에서는 2016년도에 고온기 생육 및 개화특성이 우수한 절화용 스프레이 국화 ‘Perky Star’ 품종을 개발하였다. 2012년도에 화색이 진한 노란색이면서 좁고 긴 설상화를 가진 ‘Sei-vista’ 품종을 모본(♀)으로, 화형이 좋은 ‘Amisa’ 품종을 부본(♂)으로 인공교배를 하였고 2014년부터 2016년까지 억제재배, 촉성재배, 가을재배 작형에서 생육 및 개화특성을 검정하였다. 2016년 기호도 조사를 통해 최종적으로GCS12-81-150계통을 선발하여 ‘Perky Star’로 명명하였고 2017 년에 국립종자원에 품종보호출원(제2017-64호)한 후 2018년에품종보호권이 등록(제7465호)되었다. ‘Perky Star’ 품종은 노란색 홑꽃형으로 고온에서 화색발현과 생육이 좋았으며 꽃잎이두꺼워 여름철 수출품종으로 적합하다고 판단되었다. 가을재배작형, 억제작형, 촉성작형에서 단일처리 후 개화소요일 수는 각각 49, 49, 53일, 절화장은 88.3, 84.2, 103.3cm, 꽃의 직경은 5.1, 4.8, 4.8cm, 줄기당 착화수는 25.0, 21.5, 38.8개로고온에서 절화장과 착화수가 증가하는 경향을 보였다. 흰녹병에 완전한 저항성을 갖지는 못한 품종이며, 자연개화 작형에서 절화수명은 21.3일로 대조품종 20.2일에 비해 조금 길었고, 5점 척도로 기호도를 조사한 결과 4.2점으로 대조품종 4.1과비슷한 선호도를 보였다.

다국어 초록 (Multilingual Abstract)

A new spray chrysanthemum (Dendranthema grandiflorum) cultivar ‘Perky Star’ was developed at Gyeonggi-do Agricultural Research and Extension Services, Korea, in 2016. Cultivar ‘Sei-Vista’, which has dark yellow colored flower and narrow and long ray floret, was crossed with ‘Amisa’, which has good flower shape, in 2012. This attempt was conducted to breed well-growing varieties at high temperatures period. The growth and flowering characteristics of the lines were investigated in retarding, shading and natural condition from 2014 to 2016, and a preference investigation was carried out in 2016, resulting in the GCS12-81-150 line being finally selected and named ‘Perky Star’. An application was made for a plant variety protection right for ‘Perky Star’ in 2017 (No. 2017-64), which was granted in 2018 (Korea Seed & Variety Service No. 7165). ‘Perky Star’ has single type flowers with yellow petals. This cultivar is suitable for export in summer season because it has good expression of the flower color and grows well at high temperatures and its petals are thick. In the autumn, spring, and summer cultures, the numbers of days to flowering under short day treatments were 49, 49 and 53 days, the plant heights were 88.3 cm, 84.2 cm, and 103.3 cm, the flower diameters were 5.1 cm, 4.8 cm, and 4.8 cm, and the numbers of flowers per stem were 25.0, 21.5, and 38.8, respectively. The cultivar ‘Perky Star’ was not fully resistant to white rust, showed the vase life of 21.3 days in autumn and got the preference degree of 4.2 in 5 points.
