Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain

Scientia Agricola, 2014
The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT strain tilapia (Oreochromis sp ...

Genomic Breeding Programs Realize Larger Benefits by Cooperation in the Presence of Genotype × Environment Interaction Than Conventional Breeding Programs

Frontiers in Genetics, 2020
Genotype × environment interaction (G × E) is of increasing importance for dairy cattle breeders due to international multiple-environment selection of animals as well as the differentiation of production environments within countries.

Selection of parental lines for plant breeding via genomic prediction

Frontiers in Plant Science, 2022
A set of superior parental lines is imperative for the development of high-performing inbred lines in any biparental crossing program for crops. The main objectives of this study are to (a) develop a genomic prediction approach to identify superior ...

Estimating genetic gains for tolerance to stress combinations in tropical maize hybrids

Frontiers in Genetics, 2022
Maize is a strategic food crop in sub-Saharan Africa. However, most maize growing tropical savannas particularly in West and Central African experience the occurrence of frequent droughts and Striga infestation, resulting in 30–100% yield losses.

Investigating the benefits and perils of importing genetic material in small cattle breeding programs via simulation

Journal of Dairy Science, 2023
: Small breeding programs are limited in achieving competitive genetic gain and prone to high rates of inbreeding. Thus, they often import genetic material to increase genetic gain and to limit the loss of genetic variability.
