چکیده انگلیسی
Genetic diversity and relationship of Lycoris species were investigated using SCoT marker analysis. Of 57 SCoT primers screened, 23 SCoT primers were identified to be high polymorphism. A total of 154 DNA bands with size varied from 0.2Â kb to 2.5Â kb were amplified, and 131 (82.5%) of them were polymorphic. The average number of polymorphic DNA band per primer was 5.7. Based on Nei's similarity coefficients and genetic distances, total of 43 accessions from 14 species of the genus Lycoris tested were clustered into four groups. Group I consisting of 17 accessions was further divided into two subgroup (Ia and Ib). Subgroup Ia included four species with red flower and 22 (2n) chromosomes. Subgroup Ib contained Lycoris haywardii and Lycoris albiflora which were natural hybrids with oyster white flower. Group II consisted of three species with yellow flower and 16 (2n) chromosomes. Group III was composed of Lycoris Squamigera, Lycoris incarnata and all of hybrids whose flower color was variegated. Group IV only has one species (Lycoris sprengeri) whose petal was a mixture of pink and blue. Notably, the polymorphism generated by SCoT was associated with flower color and chromosome number in this genus plants. The present data provide high-valued information for the management of germplasm, genetic improvement, and conservation of the genetic resources of Lycoris species, important horticulture and medical plants.
