Phalaenopsis ‘Blanc Rouse’ 품종은 국립원예특작과학원에서 2013년도에 육성한 신품종이다. 이 품종은 2007년에 백색 바탕에 분홍색의 소형 P. ‘KV 600’ 품종을 모본으로 하고 진한 핑크색의 P. ‘Kang 1’ 품종을 부본으로 교배시킨 후대 계통 중에서 선발하였다. 2010년에 화색, 초장, 화경 및 식물체의 생육상태 등을 고려하여 1차 선발 후 2013년에 2차 특성검정을 통하여 품종의 안정성과 균일성을 확인하고 ‘Blanc Rouse’로 명명하였다. 이 품종은 흰색바탕에 자주색 순판을 가졌으며 꽃 가운데 분홍색의 줄무늬가 크게 형성되어 있는 품종이다. 화형은 꽃잎과 꽃받침이 평편한 모양이고 꽃의 길이와 폭은 4.3cm, 4.8cm로 소형이다. 꽃대가 평균 2개 발생하며 복총상 화서로 화서당 꽃 수가 39.4개로 볼륨이 있어 소형분화에 적합하다. 자연 개화시기는 11월 하순으로 개화가 빠른 조생종 이다. 잎의 길이와 폭은 각각 17.3, 6.2cm이며 엽형은 수평이다. 기내 증식력이 높고 변이가 거의 없으며 내병성이 강하여 재배관리가 용이하다.

The Phalaenopsis cultivar ‘Blanc Rouse’ was bred by the National Institute of Horticultural and Herbal Science (Wanju-gun, Korea) in 2013. The ‘Blanc Rouse’ cultivar was derived from a cross between the miniature cultivar P. ‘KV 600’ and P. ‘Kang 1’ in 2007. In total, 182 seedlings were planted and cultivated in a greenhouse. In 2010, one line was selected on the basis of performance for traits such as flower color, plant height, leaf shape, flower stalk length, and vigorous growth; this line was given the line code “07-003-164.” A second set of analyses was carried out on the selected line with respect to cultivation characteristics and uniformity tests at farms at three different sites in Korea. This hybrid had white-colored petals (WN155A), a purple-violet lip (PVN80B), and small-sized flowers. ‘Blanc Rouse’ produces approximately 39.4 flowers per flower stalk and two flower stalks per plant. The average flower stalk length is 43.5 cm. The general impression of the petals and sepals is that they exhibit a flat shape. It has an early-blooming habit that starts in late November under optimal culture conditions. The leaves of ‘Blanc Rouse’ grow horizontally and are approximately 17.3 cm in length and 6.2 cm in width. This cultivar possesses no genetic variation and is amenable to fast in vitro propagation and easy cultivation management because of its vigorous habit and diseases resistance.
