Duck is the second-largest poultry species aside from chicken. The rate of egg production is a major determinant of the economic income of poultry farmers. Among the reproductive organs, the ovary is a major part of the female reproductive system which is highly important for egg production. Based on the importance of this organ, several studies have been carried out to identify candidate genes at the transcriptome level, and also the expression level of these genes at different tissues or egg-laying conditions, and single nucleotide polymorphism (SNPs) of genes associated with egg production in duck. In this review, expression profile and association study analyses at SNPs level of different candidate genes with egg production traits of duck were highlighted. Furthermore, different studies on transcriptome analysis, Quantitative Trait Loci (QTL) mapping, and Genome Wide Association Study (GWAS) approach used to identify potential candidate genes for egg production in ducks were reported. This review would widen our knowledge on molecular markers that are associated or have a positive correlation to improving egg production in ducks, for the increasing world populace.
鸭子是除了鸡之外的第二大家禽物种。产蛋率是家禽养殖户经济收入的主要决定因素。在生殖器官中，卵巢是女性生殖系统的主要部分，对产蛋非常重要。基于该器官的重要性，已经进行了几项研究来鉴定转录组水平的候选基因，以及这些基因在不同组织或产蛋条件下的表达水平，以及与鸭产蛋相关的基因的单核苷酸多态性（SNP）。在这篇综述中，重点介绍了不同候选基因与鸭产蛋性能的表达谱和关联研究分析。此外，还报告了不同的转录组分析、数量性状位点（QTL）图谱和全基因组关联研究（GWAS）方法的研究，用于鉴定与提高鸭子产蛋量相关的潜在候选基因。这篇综述将拓宽我们对与提高鸭子产蛋量相关或呈正相关的分子标记的认识，以满足世界人口的增长。
