Predicted Genetic Gains from Targeted Recombination in Elite Biparental Maize Populations.

Targeted recombination is the ability to induce or select for specific recombination points on chromosomes. A first study with the intermated B73 × Mo17 maize ( L.) population showed that targeted recombination doubles the predicted gains for yield and other agronomic traits.

Small ad hoc versus large general training populations for genomewide selection in maize biparental crosses.

For genomewide selection in each biparental population, it is better to use a smaller ad hoc training population than a single, large training population. In genomewide selection, different types of training populations can be used for a biparental population made from homozygous parents (A and B). Our objective was to determine whether the response to selection (R) and predictive ability (r) in an A/B population are higher with a large training population that is used for all biparental crosses, or with a smaller ad hoc training population highly related to the A/B population.

Ascertainment bias from imputation methods evaluation in wheat.

Background: Whole-genome genotyping techniques like Genotyping-by-sequencing (GBS) are being used for genetic studies such as Genome-Wide Association (GWAS) and Genomewide Selection (GS), where different strategies for imputation have been developed. Nevertheless, imputation error may lead to poor performance (i.e.
