Genetic diversity in two Lilium (Liliaceae) species from different regions of Greece based on a Random Amplified Polymorphic DNA (RAPD) analysis
Distribution of genetic variation between populations of Lilium albanicum andLilium chalcedonicum was investigated using RAPD (random amplified polymorphic DNA) profiles. Plants for the analysis were collected from four different populations, containing 33 individuals. Eleven primers yielded 88 polymorphic bands. UPGMA clustering and principle coordinate analysis indicated a clear separation between the...
