Abstract:

The objective of this study was to analyze the association of SNPs between Myf5 gene and chicken growth and reproductive traits.The SNPs of Myf5 gene in Jinghai Yellow chicken were detected by PCR-SSCP method and then the haplotype analysis was done.As a result,8 SNPs were identified in exons of the Myf5 gene.Nine haplotypes were detected in the group of 379 Jinghai Yellow chicken.For growth traits,the least square analysis showed that H1H5 had significant effects on 8 and 12 week-age-weight (P<0.05),H2H6 had significant effects on 12 and 14 week-age-weight (P<0.05).For reproductive traits,H1H5 had higher body weight in first egg than H1H4,H2H4 and H1H3(P<0.05 or P<0.01),of which,the difference between H1H5 and H1H3 was significant(P<0.01).H1H3 had a poor performance in average egg weight of 300 days.On the other hand,H1H3 had an advantage in egg number of 300 days,and higher than that of H1H4(P<0.01).The results show that SNPs of Myf5 have certain effects on growth and reproductive traits in the Jinghai Yellow chicken,and which can be used in marker-assisted selection to accelerate the chicken breeding progress.
