抄録

A total of 134 Lilium japonicum plants were collected from 39 localities in Japan. Between November 1996 and July 1997, the plants were simultaneously cultured in a field, while their morphological and physiological characters were recorded and compared between accessions of the plants. Nine of the characters recorded were associated with a geographical region or cline. 86 flowered plants were divided into five groups by a principle component analysis based on eight of the nine characters. The groups suggested the following five geographical types : 1. Wakayama and Mie Prefecture (Kii-peninsula) type : late flowering, mid-size, narrow leaves, requiring more than eight weeks from emergence to anthesis ; 2. Ranging from Shizuoka to Hyogo Prefecture type : medium flowering, mid-size, narrow leaves ; 3. Ranging from Gifu and Ishikawa to Yamaguchi and Ehime Prefecture type : late flowering, large size, wide leaves ; 4. Ranging from Niigata to Tottori and Nara Prefecture type : slightly early flowering, slightly small size, wide leaves ; 5. Discontinuous Miyazaki and Tokushima Prefectures type : early flowering, small to mid-size, deeper color of perianth. Each area in types of 1 and 5 was separated, whereas areas in type of 2, 3, and 4 overlapped from the Kinki region northward to the Chubu region.
