Bayesian analyses of genetic parameters for growth traits in Nellore cattle raised on pasture

This study was carried out to investigate (co)variance components and genetic parameters for growth traits in beef cattle using a multi-trait model by Bayesian methods. Genetic and residual (co)variances and parameters were estimated for weights at standard ages of 120 (W120), 210 (W210), 365 (W365), and 450 days (W450), and for pre- and post-weaning daily weight ga..

Population structure of jatropha and its implication for the breeding program

    D.N. Santos, J.L. Ferreira, M. Pasqual, A.L. Generoso3, T.A. Setotaw, G.M.A. Cançado and W.A. Vendrame

Jatropha (Jatropha curcas L.) has potential as an oilseed crop that requires the development of technology for its exploitation. The objective of this study was to assess the population structure and the genetic diversity in jatropha accessions at a global level using simple sequence repeat (SSR) molecular markers. Jatropha accessions (N = 109) from 10 countries were genotyped using 10 SSR mark.. Read More»

Developing selection criteria based on an ontogenetic path analysis approach to improve grain yield in barley

    T.A. Setotaw, S.G. Belayneh, R. Gwinner and J.L. Ferreira

We used correlation and path coefficient analysis based on an ontogenetic approach to develop selection criteria in barley (Hordeum vulgare L.) for an early production system in Ethiopia. A total of 100 genotypes using 10 x 10-simple lattices with two replications were used to perform the experiment at Ambo and Asasa. The combined analysis of the measured traits sho.. Read More»

Comparison of a retrotransposon-based marker with microsatellite markers for discriminating accessions of Vitis vinifera

    G.C. Sant’Ana, J.L. Ferreira, H.S. Rocha, A. Borém, M. Pasqual and G.M.A. Cançado

Identification and knowledge concerning genetic diversity are fundamental for efficient management and use of grapevine germplasm. Recently, new types of molecular markers have been developed, such as retrotransposon-based markers. Because of their multilocus pattern, retrotransposon-based markers might be able to differentiate grapevine accessions with just one pai.. Read More»

Genetic diversity of Brazilian and introduced olive germplasms based on microsatellite markers

    A.D.B. do Val, J.L. Ferreira, J. Vieira Neto, M. Pasqual, A.F. de Oliveira, A. Borém and G.M.A. Cançado

Olive trees have been grown since the beginning of civilization, and the consumption of olives and olive products is increasing worldwide, due to their health benefits and organoleptic qualities. To meet the growing market for olives, commercial cultivation of this species is expanding from traditional areas to new regions. Although the Brazilian olive industry has .. Read More»
