Use of progeny testing in beef cattle: Prediction of genetic gain in a Nelore Cattle Breeding Program
(1995-01-01)
Genetic gains predicted for selection, based on both individual performance and progeny testing, were compared to provide information to be used in implementation of progeny testing for a Nelore cattle breeding program. ...
Genetic variability in progenies of Eucalyptus dunnii Maiden for resistance to Puccinia psidii
(Crop Breeding and Applied Biotechnology, 2014-10-01)
This study investigated the genetic variability in progenies of Eucalyptus dunnii Maiden for resistance against rust (Puccinia psidii). Field experiments were installed in two regions with differentsoil-climatic conditions. ...
VARIATION ON WOOD BASIC DENSITY OF Eucalyptus urophylla S.T. BLAKE PROGENIES AT TWO SITES
(Universidade Federal de Santa Maria, 1994)
The appropriate knowledge about genetic resources potential is essential for the forest patrimony conservation and protection. It is important to emphasize the studies on variation in wood basic density conducted in trials ...
Variação genética para caracteres silviculturais e anatômicos da madeira em progênies de Myracrodruon urundeuva (Engler) Fr. Allem
(2010-09-01)
The aims of this study were to evaluate the variation and to estimate genetic parameters for silvicultural anatomic wood traits for genetic breeding of a Myracrodruon urundeuva (Engler) Fr. Allem, population from Selvíria-MS. ...
Rust resistance and mating system in Eucalyptus grandis Hill ex Maiden progenies
(Ipef-inst Pesquisas Estudos Florestais, 2017-06-01)
Populations of Eucalyptus grandis were introduced into Brazil from Queensland and New South Wales, Australia. However, in Brazil, these plants have been severely injured by rust (Puccinia psidii Winter). Therefore, we aimed ...
Influência do tamanho de parcelas experimentais na seleção de progênies de E. camaldulensis Dehnh
(2016-01-01)
In the choice of the size plots numerous factors must be considered in order to increase the efficiency of its selection, with the lowest operating cost. This work aimed to study the influence of two sizes plots in E. ...
