In a Progeny Test and Proceedings of the Genipa american L. (Rubiaceae), known as jenipapo, this study aimed to estimate the genetic variation of growth traits, the basic density of wood, dry mass of the canopy, leaf and stem in and between two populations, turn the TPP in a Seed Orchard for seedlings, as well as determining the carbon stock. For evaluation of growth traits were measured: height (m); diameter at breast height (cm) and stem form. And for biomass and carbon sequestration, there was thinning of 45 plants in TPP FEPE in Selvíria-MS, with an intensity of 16,66%. The variance components and genetic parameters were estimated by REML / BLUP method. And for the selection of the best progenies was found genetic gain from the DAP, and the Spearman coefficient. For growth traits within populations was detected significant difference in ALT and DAP, averaging 6,88 m and 9,00 cm. The characters canopy, leaf, stem and DBM also obtained significant differences, with the highest average value of the canopy with 3,74 kg. As for the analysis of the population, the DAP was the character that showed a significant difference to Mogi and Selvíria not denoted no significant difference between the characters, indicating that there is homogeneity of characters between the progenies. The average value of the greatest magnitude for both populations DAP, and Mogi (9,39 cm) and Selvíria (8,59 cm). The values of biomass were significantly different for the crown and bole to Mogi, and again Selvíria showed no significant differences. The Mogi showed average population of the crown of 4,57 kg, and the bole of Selvíria population an average of 3,19 kg. The genetic gain for the first situation to Mogi showed a gain of 3,4 cm on the average, and the second 2,4 cm. Selvíria, showed no significant gain in any of the two situations. In the first strategy of the Spearman coefficient, there was no match in 23 % of individuals. Carbon storage was higher in the...
