Abstract: The paper aims to study the diversity of agronomic traits of 50 Anthurium andrranum germplasm resources. The authors determined 11 main agronomic traits and carried out the variability, principal component and cluster analysis on the traits. The results showed that: there were wide differences among anthurium andrranum varieties, the coefficient variation was above 30% among the agronomic traits of petiole length, spathe length, spathe width and flower number; the rate of the accumulated contribution of the four major components reached 76.31%, the spathe trait had the highest feature value of all major components, it was consistent with the variability; the flower number was negatively correlated with other agronomic traits, thus other excellent traits should be considered in selecting parents. The anthurium andrranum germplasm resources were divided into four groups by clustering analysis, among them, the first Ⅰ and Ⅱ group had good comprehensive traits and could be used as important materials in future Anthurium andrranum breeding.
