Qualitative morphological similarities among hybrid Phalaenopsis in Indonesia

Abstract

Phalaenopsis spp. is one of the most popular orchid species in Indonesia and abroad. Various plant breeding efforts have increased orchids’ economic value and aesthetics. This research was conducted to study the similarity of morphological characters between orchids in eight hybrid Phalaenopsis species, namely Dtps. Shu Long King x Shu Long Purple Queen, Dtps. Fuller’s Sunset, Dtps. Shu Long Purple Queen x OX King 3545, P. Golden Tree, Dtps. OX X-Ray, P. Shu Long Romantic, Dtps. Fuller’s C-Plus 3790, Shu Long TS2904. Observation data were analyzed using the NTSys 2.02i software application. The results showed that there were two large clusters at a similarity coefficient of 0.77. Cluster 1 includes Dtps. Shu Long Purple Queen x OX King 3545, Dtps. Shu Long King x Shu Long Purple Queen, P. Shu Long TS2904, and P. Shu Long Romantic. Cluster 2 includes Dtps. Fuller’s Sunset, P. Golden Tree, Dtps. Fuller’s C-Plus 3790, Dtps. OX X-Ray. At a similarity coefficient of 0.93, there are orchids Dtps. Shu Long Purple Queen x OX King 3545 with Dtps. Shu Long King x Shu Long Purple Queen and Dtps. Fuller’s Sunset with P. Golden Tree.
