The ornamental plant market is growing, with the launch of new plants frequently occurring, which is basically due to the creation of new cultivars or the identification of native species that present desirable characteristics to the market. There are several species in the native flora that have a potential for ornamental use that has not yet been explored, among them are Mussambê (Cleome spinosa Jacq.) and Cambará (Lantana camara L.), both species are known for their medicinal properties. To enable the adequate use of these species, whether for ornamental or medicinal use, to establish efficient conservation strategies and to insert the species in genetic improvement programs, it is necessary to identify the maximum genetic variability. Thus, this study aimed to evaluate the genetic diversity present in populations of Mussambê and Cambará. The work is divided into two chapters. In the first chapter, the diversity present between and within three populations of Mussambê collected in the cities of Paraíba in Remígio, Esperança and Alagoinha is evaluated. In the second chapter, the diversity present between and within two populations of Cambará collected in Areia-PB, along PB-079 and PB-087, was evaluated. In both chapters, genetic diversity was assessed based on morphological and molecular markers of the RAPD type. Genetic diversity was accessed from the morphological data through principal component analysis and cluster analysis using molecular data. It was observed that in both species, the markers used were efficient in detecting diversity among individuals. Based on the results, in both studies, the most dissimilar individuals can be indicated as possible parents in a genetic improvement program.
