Intraspecies Relationship of Croton (Codiaeum variegatum L.) in South Parigi District Based on Phenetic Analysis

Abstract

Croton is one of the horticultural plant commodities that is important among the community because it plays a role in adding beauty and beauty and functions as a pollutant absorbent plant. This reseach is aims to describe the kinship relationship between croton cultivars. The research was conducted in May 2020. The type of research used is descriptive exploratory. The research sample used was eight croton cultivars with five individuals in each cultivar. The plant characters measured included 14 morphometric characters, six meristic characters, and 81 qualitative characters. Kinship analysis was processed using the File Editor Program (PFE) software and the Multivariate Statistical Package (MVSP). The amount of the similarity index is calculated using the Simple Matching Coefficient method, and the determination of kinship using the UPGMA algorithm. The results showed that eight cultivars were obtained and formed 3 clusters and two sub-clusters. The closest kinship relationship is between croton lele and croton with a thousand stars which are supported by a similarity index of 0.766 and the farthest relationship occurs between node 6 (croton drill, chips, crackers, catfish, thousand stars and swallow) and node 3 (croton sheep and turtles) ) which is supported by a similarity index of 0.6.
