Abstract

The Hosta 'Hwangnarae' was bred at the Korea National Arboretum, which was induced using ethyl-methanesulfonate (EMS) to obtain mutants. Among the leaf variegated Hosta plants, some with yellowish-green color pattern on the edge of the leaves was selected. They were cultivated through vegetative production. Assessment of the botanical characteristics was executed for six years from 2013 to 2018. Major characteristics such as yellowish-green color pattern on the edge of leaves appeared uniformly and was finally selected in 2019. The Hosta 'Hwangnarae' that have been bred in this way can prove to be useful as material for a ground cover plant or pot plant.

'황나래(Hwangnarae)'는 국립수목원에서 육종한 품종으로 돌연변이 유기 화학물질인 EMS를 활용하여 돌연변이 개체를 유도하였다. 변이체 선발을 통해 잎 가장자리에 황록색의 테두리가 들어간 무늬종을 선발하였다. 이렇게 선발된 개체는 영양번식을 통하여 개체 수를 늘렸다. 2013년부터 2018년까지 6년간 특섬검정을 실시하여 잎 가장자리에 황록색 무늬가 균일하게 발현되는 것을 확인한 후 2019년 최종 선발되었다. '황나래 (Hwangnarae)'는 지피용이나 분화용으로 활용적 가치가 매우 높다.
