Thirty four morphological characteristics were evaluated and coded to classify relationships among 31 Asian pears. Fruit shape was divided into multiformity from circular to pyriform in the wild and the native pears. Glossiness and lenticel of fruit skin were negatively correlated. The fruit of Pyrus phaeocarpa was the glossiest with dense lenticels. Three Korean native pears, Hawngshilli, Hwapshilne, and Chambae, had tomentose leaves but Ulleung Cheongbae and Cheongdangrori were slightly pubescent. P. babauttiagi had the longest peduncle of 7.4 ㎝ against the shortest one, Munbae, of 2.2 ㎝. Unweighted pair-group method using arithmetic averages for cluster analysis using morphological characters classified the 31 Asian pear to six groups at Euclidean distance 7.8. The six groups could be classified to two bigger groups. In accordance with fruit size, wild pears were classified into the group I to Ⅲ, whereas the native and cultivated pears were classified into the group Ⅳ to Ⅵ. Group Ⅰ was characterized by small size fruited Asian pea pears, P. hondoensis, P. lindeyi, and Indian wild pear. Group Ⅱ was divided into four taxa, Sand pear, Munbae, P. aromatica, and Ussuri pear. P. phaeocarpa constructed the group Ⅲ alone with distinctive fruit characteristics. Group Ⅳ characterized by bigger size fruited cultivars and Korean native pears. Chinese white pear, ‘Yari’, and ‘Okusankichi’ were divided into group Ⅴ. Four Korean native pears, Hoengseong Cheongri, Cheongdangrori, Cheongshilli, and Keochang Cheongshilli, were divided into group Ⅵ had elliptic to obovate shaped fruit.
