Avaliação genética do crescimento de bovinos Nelore Mocho, por meio de modelos de multicaracterísticas

Revista Ceres
RESUMO Objetivou-se, com este trabalho, estimar parâmetros genéticos para características do crescimento de animais da raça Nelore Mocho. Foram utilizados pesos corporais (Kg) ajustados aos 205 (P205), 365 (P365) e 550 (P550) dias.

Bias in the prediction of genetic gain due to mass and half-sib selection in random mating populations

Genetics and Molecular Biology, 2009
The prediction of gains from selection allows the comparison of breeding methods and selection strategies, although these estimates may be biased. The objective of this study was to investigate the extent of such bias in predicting genetic gain. For this,

INVESTIGATION OF ALFALFA LOCAL POPULATIONS FOR CREATION OF NEW BREEDING GERMPLAZM [PDF]

Poljoprivreda, 2008
Yield of dry matter and green mass are important factors in selection of fodder crop cultivars. Low genetic gain was achieved during the long time of fodder crops breeding for yield.

Sheep breeding schemes utilising artificial insemination; large-scale simulation with a complex breeding goal

Animal, 2011
Alternative Norwegian sheep breeding schemes were evaluated by stochastic simulation of a breeding population with about 120 000 ewes, considering the gain for an aggregate genotype including nine traits and also the rate of inbreeding. The schemes were:

In situ assessment of Jatropha curcas germplasm under tropical dry forest conditions in Manabí-Ecuador

Revista Facultad Nacional de Agronomía Medellín, 2020
Jatropha germplasm accessions need an assessment of their traits to evaluate the nature and magnitude of the genetic variability among accessions. The objective of this research was to evaluate the phenotypic behavior of 130 Jatropha curcas L. (Jatropha)
