| Abstract | Anthurium andraeanum Hort. cultivars are an important ornamental plant with a very high genetic diversity. Most cultivars are characterized only based on the phenotype of inflorescence which are difficult to distinguished between very closely related cultivars. This research aims to assess the genetic diversity of 26 Anthurium cultivars using inter simple sequence repeat (ISSR) markers. The ten ISSR primers generated 122 total bands and 113 polymorphic bands with an average percentage of polymorphism of 91.64%. The average polymorphism information content (PIC) was 0.26, the average effective multiplex ratio (EMR) was 10.54, the average marker index (MI) was 2.84 and the average resolving power (Rp) was 11.32. Genetic similarity matrix from Pearson coefficient between the cultivars ranged from 0.01 between Joa Sua and Cherry Pink to 0.87 between Red Bar and Sun Red, with a mean of 0.58. Cluster analysis using the unweighted pair group method with arithmetic mean analysis (UPGMA) divided 26 cultivars into two major groups. The first group comprised only Thai native foliage anthurium while the second group included all cut-flower cultivars. Although the close relate between different appearance cultivar was found. These clustering was acceptable with Cophenetic Correlation Coefficient (CCC) was 0.92. The results obtained from this study can be useful for cultivar identification and genetic diversity assessment of Anthurium. |
