Quantitative trait locus related to Opisthopapus taihangensis first laying day age and application of quantitative trait locus

The invention discloses a group of quantitative trait loci related to the first laying day age of opisthopapus taihangensis, which is positioned in an interval of chr19: 6 406070-chr19: 6 412 735 of a genome, and comprises one or more groups of significant SNP (Single Nucleotide Polymorphism) loci with physical distances of 19: 6381462, 19: 6382350, 19: 6382585, 19: 6382662, 19: 6382781, 19: 6406070, 19: 6406141, 19: 6406152, 19: 6406169, 19: 6406170, 19: 6406188, 19: 6406306, 19: 6408239, 19: 6412674 and 19: A series of SNP loci related to the first laying day age of the laying hens are developed, and the SNP loci can be used for developing molecular markers related to the first laying day age of the opisthopause chickens and primers of the molecular markers and further used for molecular marker-assisted selective breeding of the opisthopause chickens so as to obtain dominant opisthopause chickens with earlier first laying day age. 本发明公开了一组太行鸡开产日龄相关的数量性状基因座，位于基因组的chr19:6 406 070-chr19:6 412 735区间内，包括物理距离如下的显
