Abstract

A new Saxifraga fortunei 'Pinkle' was bred by crossing 'Juno' with 'Hongoan', both with light pink (RP-N66A)-colored petals. The selection of promising lines and characterization of flowers were conducted from 2004 to 2008 year in greenhouses of the Highland Agriculture Research Center, NICS, RDA. The flowering of 'Pinkle' starts on October 7 and lasted for 27 days. The number of flowers per plant is 99.7 with many flowering habits. The flower show mixed dark pink (R-P N66C) colors at opening. The flower have 5.0 petals, each have the size is 2.9 cm in width and 3.2 cm in length. Mean plant height is 15.8 cm and number of leaves are 44.3 ea. 'Pinkle' can be used as a pot flower. Fifty percent shading of the sunlight is recommended and soft rot disease occurs caused by over-irrigation. 'Pinkle' was registered as a new cultivar in Korea Seed and Variety Service in April 2011.

분화용 바위떡풀 신품종 '핑클(Pinkle)'은 화색이 연한 핑크색 품종인 '주노(朱鷺, Juno)'를 모본으로 하고 역시 핑크색인 품종인 '홍완(紅完, Hongan)'을 부본으로 하여 2004년 2월에서 4월까지 인공교배하여 종자를 얻었다. 2005년에 개화특성을 보고 4072호를 선발하였으며 포기 나누기를 하여 2005~2008년까지 증식을 하였다. 동시에 2005년~2008년까지 시설 내에서 재배를 하면서 특성검정을 한 후 최종적으로 선발하여 '핑클(Pinkle)'품종으로 명명하였다. '핑클'은 개화는 10월 7일부터 시작하여 11월 상순까지 약 27일간 100개 정도의 꽃을 피우며 화경수는 4.4개로 적지만 화경장은 15.8 cm로 안정적이었다. 화색은 진분홍색(R-P N66C)을 띠며 화경색은 붉은 색이다. 화장과 화폭이 대조품종보다 약간 큰 편이고 5개의 꽃잎이 큰대(大)자형으로 배열한다.
