Abstract
Lilium is a genus with 110 species globally. Among them, 55 species are found only in China, making this region a significant distribution zone. The Lilium species native to Midwestern China, including seven Provinces: Gansu, Shaanxi, Sichuan, Hubei, Henan, Chongqing and Yunnan, have been investigated in this study for their species categorization and morphological characterization. 16 species and 3 variants were involved in the survey: L. lancifolium, L. leucanthum, L. brownii, L. duchartrei, L. pumilum, L. davidii, L. fargesii, L. regale, L. tenuifolium, L. papilliferum, L. sargentiae, L. lophophorum, L. sulphureum, L. nepalense, L. amoenum, L. taliense, L. brownii var. viridulum, L. leucanthum var. centifolium and L. bakerianum var. delavayi. Evaluation of their botanical characteristics was then conducted. All the collected germplasm of Lilium was investigated by using the analytic hierarchy process (AHP) established on 15 indicators regarding ornamental value, exploitation potential and ecological adaptability. The result showed that L. sulphureum performed the highest ornamental value. L. regale performed the highest exploitation potential. L. lancifolium performed the highest ecological adaptability. L. regale was found as the most suitable species for sustained utilization because of its utmost AHP value. Further, L. sulphureum, L. lancifolium, L. sargentiae and L. leucanthum exhibited outstanding features for exploitation compared to the other tested species.
