Abstract：Morphological markers of 96 accessions of amorphophallus were conducted to evaluate
their level of genetic diversity．The results showed that there was remarkable genetic mutation existing
in the morphological traits of the tested amorphophallu germplasms．The average variable coefficient
between various traits of germplasms was 48.1%．Among them，the variable coefficient of bud shape
was the largest（130.6%），and that of lobes color was the smallest（25.6%）．Clustering analysis was
conducted on amorphophallus phenotypic characters．Ninty-six accessions of amorphophallus were
devided into 11 groups taking Pearson correlation coefficient 1 5 as the clustering threshold.
