Understanding Anthurium genetic diversity is essential for breeding program of  this plant. In order to study the genetic diversity of A. andreanum, 10 cultivars were analyzed using 40 RAPD and seven Start Codon Targeted (SCoT) markers. The results showed that the two of 40 RAPD markers and all of SCoT marker produced polymorphism bands. Matrix genetic distance ranged from 0.01 to 0.37 in RAPD and from 0.02 to 0.52 in SCoT marker analysis. The level of polymorphism generated by SCoT markers (100%) was similar to RAPD marker. In order to assess genetic relationships, cluster analysis was performed by method Neighbor-joining with Splits tree software. Cluster analysis for RAPD and SCoT markers revealed that cultivars were grouped in three clusters. The results from the present study suggest that the superiority of SCoT over RAPD marker techniques due to their high resolution and high variability in detection of genomic information. Moreover, it is suggested that the SCoT molecular markers have a valuable potential for evaluation and discrimination of Anthurium cultivars. This marker provides useful information to protect A. andreanum germplasm resources and also useful for further breeding programs.
