Martius) existentes en la Provincia Vaca Diez mediante descriptores fenotípicos y biométricos reproductivos. Info INIAF [online]. 2014, vol.1, n.4, pp. 23-30. ISSN 2308-250X.

In natural populations of Oenocarpus bataua C. Martius (majo) in communities: The Hondo, Santa María and 26 October Riberalta municipality, province Vaca Diez, BeniDepartment. Ranked areas (majotuzales), where selected individuals on the basis of the experiences of Community families, it was considered, the performance of pulp and oil, color of the mesocarp, size of the cluster and fruit, fruits for consumption and marketing Settled plots identifying 150 tree of two more clusters with height of less than 20 meters next to the ripening fruit. Applied the multivariate analysis of K -means, to determine clones with outstanding features and the one way ANOVA to determine differences in amount of pulp and oil according to coloration of the mesocarp. 3 individuals in the Group 2 and 14 individuals in the Group 3 have better characteristics on productivity of pulp and oil. Best pulp production lines were Group 3, for the quality of the product; consistency thick and light, purple-whitish mesocarp. Its thick product has greater consistency and lower water content; resulting in higher performance for the preparation of the "milk" by its greater dissolution of water, this is the variety most prized in peasant and indigenous communities. The weight of the fruit with free pulp seed weight, performance varies according to staining. With respect to the production of oil by the color of the pulp, fruits with purple coloration provide greater amount of oil and low amount of pulp. Fruits with mesocarp purple palms are more productive in size and number of clusters and provide greater amount of oil. The percentage of oil in the seed varies from 3% to 8%, depending on the coloration of the mesocarp and time of fruit ripening.
