title: Eight SNPs of the Myf5 gene and diplotypes associated with growth and reproductive traits in Jinghai yellow chicken.
abstract: The objective of this study was to analyze possible associations between single nucleotide polymorphisms (SNPs) in the Myf5 gene with chicken growth and reproductive traits. SNPs in Myf5 of the Jinghai yellow chicken were detected by the polymerase chain reaction single-strand conformation polymorphism method and the haplotypes were analyzed. Eight SNPs were identified in the exons of Myf5. Nine haplotypes were established in a group of 379 Jinghai yellow chickens. In terms of growth traits, least square analysis showed that haplotype H1H5 had significant effects on weight at weeks 8 and 12 (P < 0.05). Haplotype H2H6 had significant effects on weight at weeks 12 and 14 (P < 0.05). For reproductive traits, H1H5 had higher body weight for the first egg than H1H4 and H2H4 (P < 0.05), and H1H3 (P < 0.01). H1H3 had a poor performance in average egg weight at 300 days. On the other hand, H1H3 had an advantage in egg number at 300 days. The results showed that SNPs of Myf5 have certain effects on growth and reproductive traits in Jinghai yellow chickens, which can be used in marker-assisted selection to accelerate chicken genetic progress.
