Conteúdo: 	We evaluated the genetic diversity, coancestry and heritability of
an E. benthamii trial. The 115 individuals were genotyped (13 SSR) and had
their height and diameter at breast height (dbh) measured. Heritability was
estimated using the RR-BLUP and the pairwise kinship coefficient method. An
average of nine alleles per locus was observed. The expected heterozygosity
(0.655) was similar to the observed heterozygosity, with the estimated inbreed-
ing (0.02) being low. The group coancestry (0.051) demonstrates that the trees
are related to some degree. The trees were clustered in five groups using the
Evanno’s method. The average kinship within each group ranges from 0.042 to
0.082. The heritability estimated by RR-BLUP was low. The heritability estimated
using the kinship coefficients is moderate, reaching estimated genetic gains
of 14% for dbh. After knowing how genetic groups are distributed within the
population, strategies for collecting, conserving, and using these germplasm
resources can be performed.
