摘要： In this study, genetic variations among a collection of anthuriums were comparatively investigated using morphological traits and amplified fragment length polymorphism (AFLP) markers. Both morphological and AFLP-based data clustered the accessions from Anthurium andraeanum, Anthurium scherzerianum, and Anthurium clarinervium into three separate groups, with a significant though low correlation (r=0.3) observed between the morphological and AFLP-based similarity matrices. The AFLP-based principal coordinate analysis (PCoA) divided the entire accessions into three parts, reinforcing the AFLP-based clustering. Moreover, the Bayesian-based structuring assigned the anthurium accessions to three subgroups but with 27 accessions retained in the admixed groups, probably implying the highly heterozygous genome of the investigated anthuriums. The findings of this study would add new knowledge of genetic diversity among anthuriums as well as embark on a useful beginning for a rational hybridization breeding for anthuriums in future.
