Abstract: This study was carried out at the Research Station / College of Agriculture /Al-Muthanna University and Laboratories specializing in molecular genetics for the period from 1/11/2015 until 30/7/2016, to determine the relationship between the genetic markers HSC, MAF035 and BM1818 with loci 2, 3, 4, 5 alleles, 2, 3, 4 alleles and 3, 4, 5 alleles respectively, and milk production and its components. The results showed a significant differences (P 0.05) for HSC marker in ewes carrying genetic locus 2 allele in the total milk production, length of the milking season and the milk fat ratio when compared with ewes carrying genetic locus 3, 4 and 5 alleles. Also it was found high significant difference (P 0.01) for MAF035 marker in ewes carrying genetic locus 4 alleles in the total milk production, length of the milking season when compared with ewes carrying genetic locus 2 and 3 alleles, While significantly differenced (P 0.05) in the ratio of milk fat for ewes carrying genetic locus 3 alleles on the ewes carrying genetic locus 2 and 4 alleles which differed among themselves. The refered to a significant differences (P 0.05) for BM1818 marker in the ewes carrying genetic locus 5 allele in the total milk production, length of the milking season on ewes carrying genetic locus 3 and 4 alleles, while the ewes carrying genetic locus 4 alleles significantly differed in the ratio of milk fat. The results obtained a significant differences (P 0.05) for BM1818 marker in ewes carrying genetic locus 4 alleles in the proportion of non fatty solids and protein ratio which amounted 6.60 % as compared with ewes carrying genetic locus 3 and 5 alleles which have protein ratio 5.76 % and 5.06 % for both respectively.
