Abstract:Three cultivars of Narcissus tazetta var. chinensis and three cultivars of N. poeticus have been studied by RAPD (randomly amplified polymorphic DNA). Twelve 1 0-bp arbitrary primers were screened and 119 DNA bands were amplified, among which 84.86% were polymorphic. Genetic similarities were calculated using simple matching coefficient, and the phenogram was constructed by using UPGMA method. Three cultivars of N. tazetta var. chinensis were very closely related, while the three cultivars of N. poeticus were clustered together, indicating that there is a distance in relationship between the first three and the latters. It is suggested that molecular marker technique is helpful for the breeding and variety identification of Narcissus.
