Abstract

A new Doritaenopsis cultivar 'Hwasu 5205' was bred by Kyungpook National University, Korea, which produces young plants through tissue culture techniques. The new cultivar 'Hwasu 5205', showing the phenotype of vivid red and large flower type characteristics, was derived from crossing between Phalaenopsis Happy Valentine and Doritaenopsis Happy Rose. An elite individual, number '02-05-205' later named as 'Hwasu 5205', was selected among about 300 individual progenies after more than 2 years of intensive selection covering vegetative and flowering distinctiveness. In year 2004-2005, 1st and 2nd characteristic analyses were carried out through performance and uniformity tests. 'Hwasu 5205' produces vivid red (RHS #PN78B) flowers of i ncurved type with large size, of 9.2 and 12.0 cm in flower height and width, respectively. Leaves of 'Hwasu 5205' grow horizontally and are about 24.3cm in length and 8.5cm in width, respectively. This cultivar possesses no genetic variation. It can be propagated rapidly in vitro and is easy to grow due to its vigorous growth habit. 'Hwasu 5205' was registered (Reg. #: 2915) to Korea Seed & Variety Service (KSVS) on 1st December, 2009 and the PBR(plant breeder's right)is currently controlled by Sangmiwon Orchid Company, Korea.

호접란 신품종 '화수 5205'는 2002년 경북대에서 Phal. Happy Valentin과 Dtps. Happy Rose를 모부본으로 교배하여 육성한 $F_1$개체 중에서 육성하였다. 꽃은 선명하고 진한 적색의 대륜계이다. 2003-2004년 2년에 걸쳐 실생 300개체를 양성하여 이들 중에서 영양생장과 개화특성이 우수한 개체 02-05-205를 선발하였다. 2004년과 2005년에 1차, 2차 특성검정을 통하여 품종의 안정성과 균일성을 확인하고 '화수 5205'로 명명하였다. '화수 5205'는 화색이 선명하고 진한 적색(PN78B)이며, 화형은 안아피기로 안정되어 있다. 꽃의 길이와 폭은 각각 9.2, 12.0cm로 대형이다. 잎의 길이와 폭은 각각 24.3, 8.5cm이며 엽형은 수평이다. 기내증식율이 높고 변이가 거의 없으며 영양생장 우수하여 재배관리가 용이하다. 2009년 12월 1일 품종등록(등록번호 제2915호)하여 종자산업법에 의해 보호받고 있다.
