Mapping genetic diversity in European gene banks: preliminary results on chickens for the validation of IMAGE001 array

Abstract

Gene banks are a component of a national strategy for the preservation of genetic diversity. Gene bank managers need to have a global and comparable picture of the diversity in their collections in order to rationalize them. Facing a diversity of molecular tools is a difficulty. The IMAGE H2020 project aimed at developing a low cost 60k SNP array to facilitate the mapping of diversity in gene banks. The first test of this array was performed for chicken with 204 samples from 18 local breeds and nine experimental lines provided by Germany, France and Spain. The MAF across population was 0.34, showing that this tool is useful over a range of populations. The principal component analysis and the Neighbor-joining tree showed that local breeds did not cluster according to country and were generally homogenous. Comparison with on-farm populations remains to be done to assess the value of the gene bank collections.
