The aim of this work was to select progenies with high adaptability and stability from the dry rubber yield (PBS), of genotypes from a three-year-old rubber tree population, installed in three different locations (Selvíria, MS, Votuporanga, SP and Colina, SP), by the MHPRVG (harmonic average performance relative breeding values) method predicted by BLUP. The progenies were installed in a randomized block design with 30 treatments (progenies), three replications and 10 plants per plot, with spacingof 3.00 x 3.00 m (Selvíria, MS) and 1.50 x 1.50 m (Colina, SP and Votuporanga, SP). The PBS presented considerable genetic coefficient variability, ranging from 23.03 to 27.82% and average heritability ranging from 0.47 to 0.99, indicating the high value of the... |

O cupuaçuzeiro, espécie nativa da região Amazônica, encontra-se em processo de domesticação, apresentando ampla variabilidade genética e condições favoráveis para o estabelecimento de estratégias de melhoramento e conservação. O objetivo foi avaliar geneticamente 36 progênies de meios-irmãos de cupuaçu oriundos de seleção massal estratificada em áreas de produtores, com base nos componentes primários da produtividade. O experimento para seleção das progênies superiores foi instalado no delineamento aleatorizado em blocos, com quatro plantas por parcela e três repetições. Foram consideradas as variáveis de caracterização do fruto (comprimento e largura, ambos em centímetro) e componentes de produção avaliados em grama (peso médio de fruto por planta, peso... |

This work aimed at estimating genetic parameters from the vegetative stage in five populations from Jatropha curcas L. The half sib progenies were cultivated at Biojan farm, in Janaúba, MG. Plant height, stem diameter, number of branches and crown projection were assessed in all plants at three and six months old. In population 2, there was no genetic variability for all traits evaluated. The genetic gains estimated with the selection from the ten best individuals in other populations were 4% to 8% for plant height (population 1 and 4), 5% to 7% for stem diameter (population 1 and 5), 14% to 25% for the number or branches (population 3 and 5) and 9% for crown projections in population 4. According to the results obtained from this study, these populations... |

The study aimed to estimate parameters, values and genetic gain for growth traits in progenies of Eucalyptus camaldulensis, in the State of Mato Grosso. The progenies test was conducted under a randomized block design with 132 progenies, five replications and three plants in single rows, spaced 3 m x 2 m in Santo Antonio do Leverger, MT. At 24 months of age, progenies were evaluated for the characters: a) diameter at base height (DBH), in centimeters, b) total height, in meters, c) survival. The individual in the narrow sense heritability for the traits studied can be considered medium to high magnitude (0.13 and 0.21) for height and diameter, respectively. The heritability for survival were practically nil, due to low genetic variability among the... |

Heart of palm harvesting and exploitation has reduced the natural reserves of açaí and juçara; hence, the peach palm is an excellent option as source of heart of palm that can reduce the pressure on these two species. The peach palm has high tillering and no post-harvest oxidation. An experiment in a randomized block design with 72 progenies of peach palm, 36 replications and a single tree plot was performed for five years at the experimental field of Embrapa in the Western Amazon. Genetic parameters were estimated using two mixed models, one based on progeny means and the second on joint information from crops. A repeatability analysis, genotype selection, and progeny selection were performed; the Mulamba and Mock selection index was determined; and... |

Goal was to estimate genetic variability, genetic parameters and gains, as well as germination rateon teca parent trees. Seeds were collected from Cachoeiro de Itapemirim (ES) county. The trial was carriedout in the Espírito Santo Federal University. Experimental design was randomized blocks with 60 treatments,5 repetitions each and 19 plants per plot. Demonstrated genetic variability, individual heritability and parenttrees mean suggest great likelihood of genetic gain at more advanced ages. The 41, 11, 43 and 37 parent treespresented larger genetic gains associated with increase on rate and germination percentages. |

The aim of this study was to compare, through simulation, the BLUP and BLUP-HET procedures for breeding values prediction under heterogeneity of residual variances. Random data were generated with spread sheet, considering a variance of 0,10 and variable residual variance, by number of clones, in order toprovide heterogeneity of variances. Actual and residual breeding values obtained were added to the mean 10, in order to obtain positive phenotypic values. Experimental design was random blocks with 100 genotypes, one plant per plot and 2, 5, 10 and 20 repetitions. Data were evaluated using Selegen software, obtaining estimated breeding values through BLUP and BLUP-HET procedures which were compared to actualbreeding values. In this study, using two and... |
