Summary:In order to evaluate the viability and reproductive health of a seed mass of Pinus tropicalis Morelet as a management tool for a seed production center, seed production and the behavior of reproductive indicators were evaluated for three consecutive years, based on a sample of cones from 60 trees. The cones were dissected for their analysis. Potential and efficiency variables of seeds were estimated, as well as cone length, fertile scales, proportion of empty seeds, proportion of filled seeds and inbreeding estimator. The indicators were not similar for all three crops. The indicators of potential and seed efficiency were variable during the years evaluated. However, the percentage of empty seeds was higher than 15 % in all years, resulting in inbreeding estimators above the permissible for seed production areas.
