A genome-wide association study identified candidate genes associated with egg quality traits in Muscovy duck.

ABSTRACT:

Background

Egg quality directly determines embryo development in meat-type poultry. However, it is difficult to directly select the egg quality of Muscovy duck. The genes and SNPs associated with egg quality screened by GWAS can be used for molecular breeding and accelerate the progress of selection in Muscovy duck.

Result

295 Muscovy ducks were used for whole genome sequencing, and a total of 6,131,623 SNPs were obtained for further analysis. The heritability of egg quality ranged from 0.01 to 0.41, in which egg weight (EW) was 0.19, albumen weight (AW) was 0.16 and the yolk weight (YW) was 0.27. The genetic correlation of EW and AW, EW and YW, and eggshell thickness (EST) and eggshell strength (ESS) were 0.65, 0.51, and 0.74, respectively. Phenotypic correlations between e
