Estimated genetic parameters for all genetically evaluated traits in Canadian Holsteins [PDF]

Journal of Dairy Science, 2021
Genetic improvement is a crucial tool to deal with the increasing demand for high quality, sustainably produced dairy. Breeding programs are based on genetic parameters, such as heritability and genetic correlations, for economically important traits in ...

Recurrent Interpopulation Selection in Popcorn: From Heterosis to Genetic Gains

Plants, 2023
In view of the need to develop new popcorn cultivars and considering the uncertainties in choosing the most appropriate breeding methods to ensure consistent genetic progress, simultaneously for both popping expansion and grain yield, this study ...

Genetic variability for vigor and yield of robusta coffee (Coffea canephora) clones in Ghana

Heliyon, 2022
Effectiveness of plant improvement programs, especially in perennial crops like coffee, may be improved by knowing the level of genetic variation which exist within a breeding population coupled with the knowledge of estimates of genetic parameters for ...

Changes in genetic parameters for fitness and growth traits in pigs under genomic selection

Journal of Animal Science, 2020
Genomic selection increases accuracy and decreases generation interval, speeding up genetic changes in the populations. However, intensive changes caused by selection can reduce the genetic variation and can strengthen undesirable genetic correlations ...

Genetic Parameters for Age at First Calving and First Calving Interval of Beef Cattle

Animals, 2020
Simple Summary Reproductive performance of beef cows affects the profitability of beef production systems. Heritability of fertility traits is generally low, which means that there is a great influence of the nongenetic environmental factors.

Estimation of Genetic Parameters for Female Fertility Traits in the Polish Holstein-Friesian Population

Animals, 2022
The objective of this study was to estimate genetic parameters for the analyzed fertility traits of Polish Holstein-Friesian primiparous and multiparous cows, as a step toward the incorporation of new traits into routine genetic evaluation.

Genetic Parameters of Honey Bee Colonies Traits in a Canadian Selection Program

Insects, 2020
Simple Summary Genetic selection is still little applied to honey bees (Apis mellifera), whose complex genetic and reproductive characteristics are a challenge to model statistically.
