Abstract

A new $Saxifraga$ $fortunei$ cultivar 'Crystal' was bred by crossing 'Dotaerang' with light pink and light Green (RP 58D) colored petals and 'Rocksun' with light pink and light green white (RP62A + GW157A) colored petals. The selection and flower characterization were conducted from 2004 to 2007 in a greenhouse of the National Institute of Highland Agriculture. The flowering of 'Crystal' occurred from September 21 for 31 days. The number of flowers per plant was 279.0 with many flowering habit. The flower coloration was mixed light pink and green white (RP62D + GW157B) at the opening. The number of petals were 7.0, with a width of 2.1 cm and length of 1.8 cm. The plant height was 15.3 cm and number of leaves was 133.7. 'Crystal' cultivar can be used for pot flower. Fifty percent shading is a good cultural practice against direct sunlight and soft rot disease would occurs usually by over-irrigation. 'Crystal' cultivar was registered as a new variety with No. 3466 at Korea Seed and Variety Service in April of 2011 year.

분화용 바위떡풀 신품종 '크리스탈(Crystal)'은 꽃색이 연녹색 바탕에 연한 핑크색을 나타내는 품종인 '도태랑'을 모본으로 하고 역시 화색이 유사한 '록선' 품종을 부본으로 하여 2004년에 인공 교배하여 선발한 계통으로부터 육성하였다. 2005-2007년까지 3년에 걸쳐 생육 및 개화특성을 검정한 후 최종적으로 선정하여 '크리스탈(Crystal)'로 명명하였다. '크리스탈' 품종의 개화는 9월 21일부터 시작하여 10월 하순까지 약 31일간 피며 꽃 수는 279개로 많고 화경수도 11.2개로 많았으며 화경장은 15.3cm로 작아 전체적으로는 안정적인 초형이었다. 화색은 연한 녹색 바탕에 밝은 핑크색(R-P 62D + G-W 157B)을 띠며 화장 1.8cm, 화폭이 2.1cm로 작은 편이고 꽃잎 수는 7.0개로 비대(大)자형을 이루며 엽장은 3.5cm, 엽폭은 3.8cm의 크기였고 엽수는 133.7개로 많았다.
