Abstract AR
تم دراسة الاختلافات الوراثية في خطى الدجاج الاسكندرانى (الخط المنتخب L1 و الخط الكنترول L2 ) للتعرف على التنوع الوراثي و الخواص العشيرة لصفات المتعلقة بالبيض و ذلك بالخدم 8 واسمات ميكروساتيلايت.
اظهر الخط الاسكندرانى 1المنتخب ارتفاع للتكرار الجيني عن الخط المنتخب للماركر MCW241 و MCW0145 المرتبط بالموقع الذي يتحكم في صفات وزن الجسم و العمر عند أول بيضه و سمك قشرة البيض عند عمر 53 أسبوع.
في الوقت نفسه الماركر ADL188و MCW 246 و MCW0170 المرتبطة بمواقع صفات وحدات هوة، متانة قشرة البيض و وزن البياض عند 33 أسبوع اظهر انه لا توجد اختلافات بين الخط المنتخب و الخط الكنترول .
لوحظ أيضا أن التباين غير معنوي بين الخط المنتخب 16 جيل و خط الكنترول لصفة البروتينات الذائب لقشرة البيض.نستنتج من هذه الدراسة أن الانتخاب للنضج الجنسي المبكر فان وزن الجسم و سمك القشرة يتحسن.
Abstract EN
Two lines of Alexandria chicken (selected L1 and control L2) were characterized for their genetic diversity and identified population priorities for egg traits.
Eight microsatellite markers linked to QTLs associated with the studied egg traits were used.
The selected Alexandria line L1 showed higher frequency, than the control lineL2, of loci associated with MCW241 and MCW0145 markers that might be associated with body weight (BW), age at first egg (AFE) and Shell thickness at 53 weeks of age (ST53) traits.
Meanwhile the tested markers, ADL188, MCW 246 and MCW0170 that are associated to Haugh units (Hu), egg shell strength (ESS) and albumin weight at 33 weeks of age (AW33), didn't show frequency differences between the control and the selected lines.
No significant variation was observed between the selected lines and the control line in eggshell soluble protein.
In conclusion, our current study indicates that, selection for early age of sexual maturity; the body weight, and shell thickness were improved.
