Optimizing the Construction and Update Strategies for the Genomic Selection of Pig Reference and Candidate Populations in China.

ABSTRACT: Optimizing the construction and update strategies for reference and candidate populations is the basis of the application of genomic selection (GS). In this study, we first simulated1200-purebred-pigs population that have been popular in China for 20 generations to study the effects of different population sizes and the relationship between individuals of the reference and candidate populations. The results showed that the accuracy was positively correlated with the size of the reference population within the same generation (r = 0.9366, p < 0.05), while was negatively correlated with the number of generation intervals between the reference and candidate populations (r = -0.9267, p < 0.01). When the reference population accumulated more than seven generations, t
