| description | Forest tree breeding activities in plantations with exotic species implies several instances of material selection where genetic variation can be affected. The objective of the work was to verify the genetic variability present in two plantations of Pinus caribaea var. hondurensis by microsatellite markers, initially designed for Pinus taeda. Thus, 299 individuals were analyzed using eight polymorphic microsatellite markers. The results indicate that both plantations have adequate levels of genetic diversity that are representative of the Pinus genus. Through the Bayesian method, it was possible to detect two different population genetic structure(K = 2) between both plantations analyzed. In conclusion, this study suggests that microsatellites markers are useful tools to monitor genetic variation in genetic breeding programs. The genetic diversity estimated in both plantations is similar and typical for Pinus plantations, and as expected, there was a slight decrease in genetic variability in the commercial plantation in comparation with the base plantation. |

As atividades de melhoramento genético florestal em plantios com espécies exóticas envolvem várias instâncias de seleção de material, onde a variação genética pode ser afetada. O objetivo do trabalho foi verificar a variabilidade genética presente em duas plantações de Pinus caribaea var. hondurensis através de marcadores microssatélites, inicialmente desenhados para Pinus taeda. Assim, 299 indivíduos foram analisados utilizando oito marcadores microssatélites polimórficos. Os resultados indicam que ambas plantações têm níveis adequados de diversidade genética que são representativos do gênero Pinus. Através do método Bayesiano, foi possível detectar duas populações genéticas estruturadas (K = 2) entre as duas plantações analisadas. Em conclusão, este estudo sugere que os marcadores microssatélites são ferramentas úteis para monitorar a variação genética nos programas de melhoramento genético. A diversidade genética estimada em ambas plantações é semelhante e típica das plantações de Pinus, e como se esperava verificou-se uma ligeira diminuição da variabilidade genética na plantação comercial, em comparação com a plantação base.
