Estimativas de parâmetros genéticos, correlações e índices de seleção para seis caracteres agronômicos em linhagens F8 de soja
(2016-08-01)
This study aimed to estimate genetic and phenotypic parameters and provide knowledge for breeding programs aiming at the selection of the main characters of assessment in soybeans. The experiment was installed in Sabia ...
Analysis of genetic correlations of hip height with selection indices and mature weight in Nelore cattle
(2013-01-25)
Body size is directly related to the productive and reproductive performance of beef cattle raised under free-range conditions. In an attempt to better plan selection criteria, avoiding extremes in body size, this study ...

Genetic association among feeding behavior, feed efficiency, and growth traits in growing indicine cattle
(2020-01-01)
This study aimed to estimate genetic parameters, including genomic data, for feeding behavior, feed efficiency, and growth traits in Nellore cattle. The following feeding behavior traits were studied (861 animals with ...
Comparison of selective genotyping strategies for prediction of breeding values in a population undergoing selection
(Amer Soc Animal Science, 2012-12-01)
Genomewide marker information can improve the reliability of breeding value predictions for young selection candidates in genomic selection. However, the cost of genotyping limits its use to elite animals, and how such ...
Correlations and path analysis in soybean progenies with resistance source to cyst nematode (race 3)
(2019-01-01)
Path analysis is an important study that slices the correlation coefficients between two variables to evaluate whether the relationship between them is of cause and effect. This study aimed to estimate the phenotypic and ...
Direct and correlated responses to artificial selection for high and low knockdown resistance to high temperature in Drosophila buzzatii
(Pergamon-Elsevier Science Ltd, 2010-07)
Knockdown resistance to high temperature (KRHT) is a genetically variable trait for thermal adaptation in insects. Selection for KRHT may affect a number of fitness components as well as resistance to several forms of ...
