Abstract

We report a technique for obtaining seeds of 'Cheongnarae' (a variety of Hosta minor cultivated at the Korea National Arboretum in 2019) by artificial crossing of H. minor, collected from Jeju Island, as the female parent and H. minor 'Krossa Regal', cultivated outside Korea, as the male parent. Among the individuals obtained after sowing, those that showed different morphological characteristics, such as leaf shape and color, were selected. Among these individuals, those with thick leaves and light-colored flowers were further selected. Vegetative propagation and cultivation steps were repeated for evaluation of the characteristics. 'Cheongnarae' has relatively thicker leaves and a darker color (RHS 137A) than the control variety 'Black Hills' and has wings at the point where the petiole meets the leaf blade. The shape of the leaf blade edge is clearly sinuous, and the flower color is close to white (White N155B). 'Cheongnarae' cultivated in this way can be used for pot plant or gardening.

'청나래'는 국립수목원(Korea National Arboretum)에서 2019년에 육성한 품종이다. 제주도에서 채집한 좀비비추(H. minor)를 모본으로, 외국에서 육성된 H. 'Krossa Regal'을 부본으로 인공 교배하여 종자를 채종하였다. 파종 후 얻은 개체 중 잎의 모양, 색깔 등의 형태적 특성에 차이를 보이는 계통을 우선 선발하였다. 이 중, 잎이 강건하고 화색이 연한 개체를 선발하여 영양번식과 재배를 반복하며 특성 고정 및 검정을 실시하였다. '청나래'는 대조품종인 H.'Black Hills'과 비교하여 잎이 두텁고 색이 진하며(RHS 137A) 잎자루(petiole)와 잎몸(leaf blade)이 만나는 부위에 날개가 있다. 잎몸 가장자리는 물결 모양이 뚜렷하고 화색은 흰색(White N155B)에 가깝다. 이와 같이 육성된 청나래는 분화 또는 정원용으로 활용이 가능하다.
