Abstract

Lilium lancifolium, which is one of the Korean native lilies, possesses several useful genetic characteristics such as growth vigor, bulbil formation and resistance to Fusarium. Hybridization was performed to insert useful traits of Asiatic hybrid "Dreamland" as the male parent with upward direction and dark brown spotless on the petal into L. lancifolium as the female parent. The rate of pollen germination of L. lancifolium and "Dreamland" were 30% and 60%, respectively. The pollen germination ratio of $F_1$ progenies at flowering date was 25-57%, which is between the parents'pollen germination ratio. The individual flowering time was between 113 days and 131 days after planting. Of 99% of all plants, the leaf shape index was more than five, which means that the leaf shape of $F_1$ plants is more influenced by female than male parent. The flower color was separated into four types. 51.5% of the progenies showed orange and 44.2% showed light orange, respectively. The colors seemed to be highly influenced by female parents. Mixed colors of parents, orange yellow and light yellow orange, were 3.1%, 1.2%, respectively. Flowering directions were segregated by three different ways, upside, side, and downside. Side direction, which is medium type between female and male parent, was 73%. All progenies showed lots of spot on petals except one offspring. The percentage of bulbil formation on leaf axil was 49.4%. Among those, the maximum number of bulbil formation was 25. The mean number of bulbil formation per plant was five.

참나리(Lilium lancifolium)는 우리나라 자생나리로 생육이 왕성하고 후자리움에 내성이 있으며 주아를 형성하는 등 많은 장점을 가진다. 이를 자방친으로 하여 Asiatic hybrid "Dreamland"의 상향이고 흑갈색의 반점이 없는 형질을 이입시키기 위해 교배를 수행하였다. 참나리와 "Dreamland"의 화분발아율은 각각 30과 60%이었다. 이들 후대의 개화일자별 화분의 평균 발아율은 25-57%로 양친의 중간에 분포하였다. 개화는 정식 후 124일째 가장 많았다. 엽형지수는 5 이상인 식물체가 약 99%로 나타나 자방친인 참나리의 영향이 우세하였다. 화색은 4가지로 분리되었다. Orange와 light orange가 각각 51.5와 44.2%로 대부분을 차지하여 자방친의 영향이 우세하였다. 그리고 양친의 중간색인 orange yellow와 light yellow orange는 각각 3.1과 1.2%로 분리되었다. 꽃잎의 반점은 1개체를 제외한 나머지 모든 개체에서 관찰되었다. 개화 방향은 상향, 측향 및 하향 3가지로 분리되었다. 측향 즉, 자방친과 화분친의 중간형이 73% 이었다. 주아는 49.4% 형성되었으며 그 중 최대 25개까지 착생되었다. 평균 주아수는 5개이었다.
