Genetic Diversity of some Daffodil (Narcissus L. spp.) Genotypes in Turkey by Using SRAP Markers
Daffodil (Narcissus L. spp.) is one of the oldest ornamental flowers that have been cultivated from ancient times to nowadays. The species Narcissus tazetta L. and N. serotinus L. have spread out in different regions of Turkey and some other species have been naturalized. The purpose of this study was to characterize some daffodil populations that were collected from different regions of Turkey by using SRAP markers. Twenty-two daffodil populations of different species such as N. tazetta, N. serotinus, N. pseudonarcissus L., N. poeticus L. and N. jonquilla L. were used. Thirty-seven of 48 SRAP primer combinations showed scorable and polymorphic bands between samples. The similarity coefficients were used to construct a dendrogram by Unweighted Pair-Group Method with Arithmetic Averages (UPGMA) using NTSYS-PC. Cophenetic correlation between ultrametric similarities of tree and similarity matrix were high (r = 0.97). The genotypes of Narcissus species were divided into 2 main groups. Although there was less genetic variation among N. tazetta species, even collected from different regions of Turkey, N. poeticus, N. pseudonarsis, N. jonquilla and N. serotinus had more genetic divergence among them. It can be concluded that genetic variation of Narcissus species can be used for daffodil breeding programs.
