Estimation of Least Squares Means and Non-genetic Factors for Reproduction Traits in Frieswal Cattle under Field Progeny Testing

Indian Journal of Animal Research
Background: The reproduction traits are quantitative traits governed by polygenic inheritance and influenced by non-genetic managemental factors to a greater extent as their heritability values are low. This investigation was undertaken to study the effect of period and season of calving in Frieswal cattle under field progeny testing programme. Methods:

Comment on “Selection system efficiencies for computer-simulated progeny test field designs in loblolly pine” J. A. Loo-Dinkins, C. G. Tauer and C. C. Lambeth

Theoretical and Applied Genetics, 1991
Loo-Dinkins et al. reported relatively poor 'realized' gains from selecting individuals on departures from the means of small multi-tree plots. This could be largely attributed to disregarding a heritability of plot effects.
