【 摘 要 】

Paphiopedilum (Slipper Orchid/Venus orchid) is a genus belongs to subfamily of Cypripedioideae. All Paphiopedilum species are covered by the Convention on International Trade in Endangered Species (CITES). Cluster analysis has been used to grouping of plant variation. The aim of the research was to estimate the relationship between parents (Paph. Maudiae "Black" & Paph. tonsum) and their 19 progenies. 23 morphological Qualitative traits and 13 morphometrical/quantitative traits were used in multivariate analysis. The morphological qualitative data was scored numerically as present (1) and absent (0), and then analyzed using NTSYS PC (Rohlf, 1998). Similarity between accessions was estimated using Dice coefficient. Average taxonomic distance was used to group the quantitative data using Dist coefficient. Result showed that hierarchical clustering of 21 genotipes indicated two main groups based on qualitative data as well of quantitative data. Group 1 had 5 accessions (PH1-01, PH1-16, PH1-51, Ph1-73, PH1-78, and group 2 had 10 accessions. Four accessions were separated and stand alone. Group 1 had morphological resemblance with Paph. Maudiae and group 2 had morphological resemblance with Paph. Maudiae and Paph. tonsum. Based on quantitative data, group 1 (11 accessions) had quantitative trait resemblance with Paph. Tonsum. Group 2 (7 accessions) had quantitative trait resemblance with Paph. Maudiae. Morphological trait of Paph. Maudiae was dominant inherited to their progenies.
