Abstract:

In this study, genetic relationships among 10 cultivars of Ti plant (cordyline fruticosa) were estimated on the basis of morphological characters and RAPD data. Twenty five morphological characters were analyzed with an unweighted pair-group method using an arithmetic average (UPGMA). For RAPD analysis, forty 10-mer random primers were selected and 126 polymorphic bands, ranging from 0.2 kbp to 2.0 kbp, were obtained. UPGMA cluster analysis using Nei and Li's distance coefficient were then performed. Moreover, the results based on different data were similar.
