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
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 F1 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 F1 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.
