Evaluation of selection criteria in laying quail (Coturnix coturnix japonica)
(2019-09-01)
The primary aim of the commercial exploration of quail in Brazil is to increase egg production. The characteristics of the genetic groups used are not well known, making it difficult to increase eggs production. The objective ...
Optimum genetic contribution applied to the selection of Santa Ines sheep
(Empresa Brasil Pesq Agropec, 2016-06-01)
The objective of this work was to evaluate strategies of simulated selection by optimum contribution for the genetic gain, with restriction on coancestry, for the weight trait of 84-day old Santa Ines sheep. The analyses ...
A predetermined proportional gains eigen selection index method
(Crop Science Society of America (CSSA), 2017)
Expected gains with selection from the simultaneous selection of different quantitative traits in progenies of Eucalyptus camaldulensis DEHNHGanhos esperados com a seleção a partir da seleção simultânea de diferentes caracteres quantitativos em progênies de Eucalyptus camaldulensis DEHNH
(2019-01-01)
This study aimed to compare the gains obtained with three selection indices and direct and indirect selection applied to the individual genetic values in progeny tests of E. camaldulensis, at the age of six; for shape of ...

Using additive indices and principal components to select sexual genitors and hybrids of Urochloa decumbens
(Brazilian Soc Plant Breeding, 2020-01-01)
The selection of sexual genitors in Urochloa decumbens breeding is dependent upon the performance of their progeny for several traits simultaneously. Thus, our objectives were to (i) compare the efficiency of indices to ...
Seleção simultânea de caracteres em progênies de Pinus caribaea Morelet var. bahamensis
(2004-12-01)
In order to obtain superior materials, the selected genotype needs to simultaneously have a group of favorable attributes and give a higher yield, so as to satisfy both the consumer and the producer. The objective of this ...

Two-Way Selection for Daily Gain and Feed Conversion in a Composite Rabbit Population
(1997-09-01)
We conducted a two-way selection experiment in a composite rabbit population to investigate the responses to selection for postweaning ADG and feed conversion (FC). Two generations of crossing, followed by four generations ...
