Morphometric studies of fruits and forest seeds may indicate the presence of variability among individuals of the same species. The objective of this study was to investigate the morphometric diversity of fruits and seeds of Swietenia macrophylla in 20 individuals belong to the Parakanã Indigenous Land, PA, Brazil. The following characteristics of the fruits, wingless seeds, and seeds without testa of the 20 trees were evaluated. Analysis of variance was performed on the collected data, followed by test of the means by Scott-Knott test. Genetic dissimilarity was assessed through means of the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) grouping technique and canonical variables (CV). The results indicate high phenotypic diversity among mahogany fruits and seeds and the grouping of trees regardless is of the location of the indigenous village. Thus, mahogany trees have high genetic potential for germplasm conservation, seed harvesting, and breeding programs.
