| This study aimed to estimate the parameters related to the genetic control of the physical characteristics of the fruits, oil content, and oil yield, and to proceed with the selection of macaw palm accessions. Forty-four macaw palm accessions of the active germplasm collection of the Federal University of Viçosa were collected for the evaluation of epicarp dry matter, pulp dry matter, endocarp dry matter, kernel dry matter, oil content, and oil yield. Narrow-sense individual heritability estimates were considered as of intermediate magnitude. The coefficient of repeatability and the accuracy in family selection was of high magnitude. Oil yield per plant presented the highest coefficient of individual genetic variation. Five different accessions contributed... |

| This study aimed to estimate genetic traits, determine genetic correlation, and predict breeding values as a way to select macaw palm accessions from the Germplasm Bank of the Universidade Federal de Viçosa, Minas Gerais, Brazil. This trial was carried out via REML/BLUP method, which was applied to following parameters: precocity (PREC), height of the first spathe (HFS), total fruit number (TFN), pulp oil content (POC) and oil production per plant (PROD). Thirty-six accessions -comprised of two to ten plants each -were evaluated. Selegen-Reml/Blup software was used for genetic analysis as well as to identify individuals to compose the population to be exploited in macaw breeding in both short-and long-term programs. The highest correlation coefficients... |

| Macaw palm (Acrocomia aculeata) is a promising species for use in biofuel production, and establishing breeding programs is important for the development of commercial plantations. The aim of the present study was to analyze genetic diversity, verify correlations between traits, estimate genetic parameters, and select different accessions of A. aculeata in the Macaw Palm Germplasm Bank located in Universidade Federal de Viçosa, to develop a breeding program for this species. Accessions were selected based on precocity (PREC), total spathe (TS), diameter at breast height (DBH), height of the first spathe (HFS), and canopy area (CA). The traits were evaluated in 52 accessions during the 2012/2013 season and analyzed by restricted estimation maximum... |
