Genetic diversity provides parameters to characterize the population and choice of parents. For the study in a population agronomic and morphological characters can be used which, when subjected to multivariate biometric techniques, allows multiple unify information from a set of characters. The aim of this study was to identify the genetic diversity of 13 Australian king palm progenies by Tocher method from five phenotypic variables that are associated with heart of palm yield. Thirteen progeny Archontophoenix spp were sown in Itajaí - SC in the design of the randomized block with six replicates and eight plants per plot. The five characteristics evaluated were: plant height (one year before the harvest), plant height and stem diameter (at harvest), premium heart-of-palm and edible basal stem yield. The harvest occurred in 3.5 years after planting and the data analyzes were performed using the GENES software. As measures of Mahalanobis distances (D2), the values ranged from 0.72 between progenies 2 and 4 - being the most similar genotypes - up 148.63 between genotypes 10 and 13 - being the most divergent. The use of Tocher optimization method, based on the dissimilarity D2, enabled the distribution of progenies studied in four groups. Group I was composed of nine progeny (69%) - these being 1, 2, 3, 4, 7, 8, 9, 11 and 12, group II was composed of two progenies (5 and 6) and groups III and IV composed for one progeny each, 10 and 13, respectively. The intra-group distances were always lower than at any intergroup distance, taking into account the criteria established for the Tocher optimization method. In groups I and II, which have more than one progeny, the average intra-group distances were 9.76 and 6.89, respectively. Among the six intergroup distances, the values ranged from 22.29, between groups I and II, up 148.63, between groups III and IV. The relative contribution of characters for genetic diversity were 42.54% for edible basal stem, 30.73% for plant height at harvest, 18.18% for plant height a year before the harvest, 7.14% for premium heart-of-palm and 1.40% for stem diameter. For this there are genetic differences between genotypes and the yield of edible basal stem and stem diameter, respectively, more and less contributed to genetic diversity.
