<![CDATA[The study carried out in the first research station to the College of Agriculture-Al-Muthanna University, 12 km south west of Muthanna district and laboratories specializing in molecular genetics for the period from 15/11/2017 until 30/4/2018 in order to determine the relationship between genetic markers BM1258 and INRA023 with genotypes (90/125,120/135,95/140 and 100/90) and (190/220.180/200 and 185/170) bp Respectively and the production of milk and Its components the following are the most important results obtained: The presence outweigh the significant (P≤0.05) for marker BM1258 in ewes carrying genetic site 90/125 bp in the total production of milk and the length of the milking season the ewes bearing on others local 120/135 , 95/140 and,100/90 bp .while outperformed significantly (P≤0.05) ewes 120/135 bp genetic location in the proportion of fat significantly milk ewes bearing two hereditary 90/125 and 95/140 bp, which varied among them. The presence outweigh the significant (P≤0.05) for marker INRA023 in ewes bearing site genetic 185/170 in the total production of milk and the length of milking the ewes carrying two 190/220 and 180/200 season, while the superiority of ewes same location genotype 180/200 in the percentage of milk fat. Affected the results and there is a significant difference (P≤0.05) for Marker INRA023 in ewes same location genotype 180/200 bp in the proportion fat solids and protein content.Keywords: Sheep, Genetic markers, BM1258, INRA023.]]>
