Likelihood ratio tests (LRT) were applied in an unbalanced provenance/progeny test of mate (Ilex paraguariensis A. St. Hil.). The trial was established in a randomized complete block design with seven provenances, 140 half sib families, ten blocks and six plants per linear plot. The spacing was 3 m x 2 m. The following conclusions were obtained from the deviance analysis (Anadev): all random effects and associated variance components and coefficients of determination (heritability and coefficients of determination of plots and provenances) were significant; there is enough genetic variability in both within and between provenance levels which can be adequately explored for breeding purposes.doi: 10.4336/2010.pfb.30.62.157 Tipo: Info:eu-repo/semantics/article Palavras-chave: Anadev; Ilex paraguariensis; Progeny test Anadev; Ilex paraguariensis; Teste de progênie..

PFB - Pesquisa Florestal Brasileira Kalil Filho, Antonio Nascim; Sturion, José Alfredo. This work aimed to analyze the performance of peach palm progenies seeds and to estimate genotypic values (additive and dominant effects) and heritability in the broad sense for seed weight collected in 40 trees. Heritability in the broad sense and not in the narrow sense was considered because a major amount of the variability for seed weight arises from the mother trees. The analysis of variance showed highly significant differences between progenies for seed weight. Heritability in the broad-sense was 0.95. The genetic values accumulated in the ten better trees ranged from 1.73 to 0.25, while genetic percentage gains ranged from 68% to 23%, showing a high amount of genetic variability for seed weight. This characteristic is potentially related to early... Tipo: Info:eu-repo/semantics/article Palavras-chave: Effective effects; Genetic gains Efeitos aditivos; Ganhos genéticos.

Ilex paraguariensis St.Hil., popularly named erva-mate in Brazil, is an indigenous species of the Araucaria Forest with a large geographic distribution and a high social and economic importance. The seeds of this species exhibits physiologic and seed coat  impermeability dormancies and needs stratification on sand in order to break them. This work aimed to evaluate the influence of genotype -environment interaction on embryo development of erva-mate seeds formed under different environmental conditions. The fruits were collected in Cascavel, Toledo and Campo Mourão, State of Paraná, and in Soledade, State of Rio Grande do Sul, in February 2003. The experiment was carried out on Forest Seed Laboratory of Embrapa Florestas, in a completely randomized design...

A provenance/progenies trial of grevílea (Grevillea robusta Cunn.) was established in the Ponta Grossa region, state of Paraná, Brazil. The purpose was to identify genetically superior individuals in order to assure good material for future seed orchard. The genetic matherial was based on 60 half-sib progenies from eighteen Australian provenances and one control. Progenies were evaluated in randomized blocks with seven replications, five plants per plot and spacing of 3 m x 3 m (9 m2 per plant). Significant gains were estimated through selection of the 200 best trees (23,33%), for cilindric volume, at 10 years age, based on genetic values, aiming to establish a seedling seed orchard; or selecting the best twenty trees (33,33%), towards a clonal seed orchard.
