对96份魔芋种质进行形态学标记，以评价魔芋种质的遗传多样性水平。结果表明：供试魔芋种质的形态学性状均存在显著的遗传变异，种质间各性状平均变异系数为48.1%，其中芽形状的变异系数最大，为130.6%；裂片颜色的变异系数最小，为25.6%。对魔芋表型性状进行聚类分析，以Pearson相关系数15作为聚类阈值，将96份魔芋品种分为11类。

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 15 as the clustering threshold.
