Abstract: Currently, there is a lack of emphasis on the ornamental value evaluation and germplasm collection of Coffea liberica in China, making it difficult to systematically select outstanding C. liberica clones, which also restricts the commercial cultivation and application of superior selections of C. liberica in landscapeing.. In Hainan Island 128 individual seedling trees of C. liberica germplasm were selected for survey and statistical analysis of their ornamental traits Four evaluation criteria such as C1 leaf, C2 fruit, C3 flower and C4 others, and 14 evaluation factors were selected by using the analytic hierarchy process（AHP） to establish an evaluation system for the ornamental traits of C. liberica in Hainan Island. Meanwhile, the ornamental grades of 128 Coffea liberica individual seedling trees were evaluated to provide reference for landscape application and selection of elite ornamental individuals. The results show that in the overall ranking value C2（0.534） fruit has the highest weight, followed by C1（0.240） flower, which indicates that the ornamental traits of flowers and fruits have significant impact on the ornamental evaluation of C. liberica resources. Among the 14 evaluation indicators, P4mature fruit color（28%）, P6 fruiting period（17.8%）, and P10 number of flower branches（13.8%） are the main indicators affecting the ornamental value of C. liberica. Based on the comprehensive index score, 63 superior C.liberica individual plants were selected, which can be an important resource for landscape application. In conclusion, the AHP method can be effectively used to conduct a comprehensive evaluation of C. liberica germplasm, and select the most suitable individual plants for landscape application in Hainan, laying a foundation for their widespread promotion in gardens.
