蛋壳颜色遗传机理研究进展

Genetic Research Progress of Eggshell Color

鸡蛋蛋壳颜色作为一个直观的经济性状,长期以来备受关注。在中国,颜色均一的鸡蛋深受消费者青睐。但是由于不同品种鸡所产蛋壳颜色深浅不同,同一品种不同个体间蛋壳颜色也存在一定差异,因此提高群体蛋壳颜色均一性成为育种者不可避免的问题。本文详细叙述了蛋壳颜色的基本性质,同时介绍了蛋壳颜色的遗传模式及控制蛋壳颜色的基因与QTL,旨在从分子水平上揭示影响蛋壳颜色的决定因素,为育种目标及育种方案的制定提供参考。

Eggshell color is an important intuitive economic trait and attracts much attention for a long time.In China,uniform color eggs gain more popularity among consumers.However,different chicken breeds produced eggs with different eggshell color,and even in the same breed,there is difference in eggshell color among different individuals.Thus,it is inevitable to improve the uniformity of eggshell color for breeders.To reveal the determinants for eggshell color at the molecular level,this review elucidated the basic property of eggshell color and discussed its genetic patterns,genes and QTLs involved in eggshell color regulation,which would provide reference for designing breeding goals and breeding program.
