Abstract

A Hosta cultivar 'Neulpureum 1' was bred at the Korea National Arboretum, which produces new cultivars using vegetative propagation techniques. The new cultivar 'Neulpureum 1' was derived by crossing Hosta minor with Hosta 'Krossa Regal'. Among the induced leaf-color- and shape-modified hosta plants, the plants that exhibited deep-green color and small-bended leaves were selected. 'Neulpureum 1' maintained the deep-green leaves for longer than Hosta 'Krossa Regal'. Additionally, the plant height of 'Neulpureum 1' was shorter than that of Hosta 'Krossa Regal' and several leaves were observed on the new cultivar; therefore, it is likely to be used as a pot plant. The botanical characteristics were investigated for three years beginning 2012. A Hosta 'Neulpureum 1' can prove to be useful as a material for a pot plant or as ground cover plant at half-shadow place.

'늘푸름 1 (Neulpureum 1)'은 국립수목원에서 육종한 품종으로, 좀비비추와 원예품종인 Hosta 'Krossa Regal'을 교잡 후 얻은 개체를 특성에 따라 선발하여 육종하였다. 선발은 잎의 색이 진하고 잎에 존재하는 굴곡의 크기가 작은 개체를 기준으로 하여 선발하였다. 그 결과 대조품종에 비해 짙은 녹색을 유지하는 기간이 길고, 초장이 짧으며, 풍부한 잎을 가지고 있는 개체가 선발되었다. 이렇게 선발된 개체는 무성증식방법으로 개체수를 늘렸으며, 3년간 재배하며 특성을 고정 및 조사하였다. 이렇게 육종된 '늘푸름 1 (Neulpureum 1)'은 가지고 있는 특징 때문에 반음지의 지피용 뿐만 아니라 분화용으로도 이용될 수 있는 만큼 활용적 가치가 매우 높은 신품종이다.
