Genetic Relationship Analysis among Oakleaf Loquat, Daduhe Loquat and Common Loquat Based on Morphologic Traits

Based on morphologic traits including 18 traits of leaf and fruit, the genetic relationships among Oakleaf loquat (E. prinoides), Daduhe loquat (E. prinoides var. dadunensis) and Common loquat (E. japonica) were investigated in this study. The results showed that Oakleaf loquat, Daduhe loquat and Common loquat displayed very significant differences. Many traits of Daduhe loquat were between Oakleaf loquat and Common loquat and some of the other traits were lean to Oakleaf loquat while some were lean to Common loquat. The results of comparative analysis and cluster analysis support that Daduhe loquat was hybrid of Oakleaf loquat and Common loquat.
