Ancestor-inclined distribution characteristics and genetic relationship analysis of Malus taxa. According to the Malus species taxonomy system proposed by Rehder (1940) [28], Yu et al. (1956) [29], and Li et al. (2001) [30], the 31 species involved in this study belonged to seven sections (series): I, Sect. Docyniopsis (one species); II, Sect. Chloromeles (three species); III, Ser. Yunnanenses of Sect. Sorbomalus (three species); IV, Ser. Kansuenses of Sect. Sorbomalus (three species); V, Ser. Sieboldianae of Sect. Sorbomalus (three species); VI, Ser. Baccatae of Sect. Eumalus (six species); and VII, Ser. Pumilae of Sect. Eumalus (12 species). The order from I to VII corresponded with the sequence of sect/series evolution. Species in the same section (seris) were labeled with the same color. Then the ancestor-inclined distribution characteristics of Malus taxa were analyzed from two aspects: species and cultivars, based on the clustering dendrogram of all 142 Malus taxa
