Özet
Bu araştırma, Akkaraman, İvesi ve bunların Alman Siyah Başlı ve Hampshire Down etçi ırkları ile F_1 ve B_1 melezlerinin yapağı verim ve özelliklerini incelemek amacı ile yapılmıştır. Araştırmada, 1995-1996 yıllarında elde edilen toplam 622 kırkım kaydı kullanılmıştır. Yapağı verim ve özelliklerine, genotip, yaş, kırkım yılı, cinsiyet ve kırkım sonu vücut ağırlığının ve bunların etkileşimlerinin etkileri Genel Doğrusal Model (General Linear Model, GLM) ile analiz edilmiştir. Kirli gömlek ağırlığına incelenen tüm faktörlerin; lüle uzunluğuna cinsiyet dışındaki faktörlerin; elyaf çapına genotip, cinsiyet ve kırkım yılının; ondulasyon sayısınaa ise sadece genotipin, kemp ve medulla oranına kırkım yılı ve genotipin etkisi önemli bulunmuştur. Kirli gömlek ağırlığı, lüle uzunluğu, elyaf çapı, ondulasyon sayısı ve kempli-medullalı elyaf oranı, sırası ile, Akkaramanlarda 2.31 kg, 12.16 cm, 29.19 \mu , 5.44 adet ve %1.30; İvesi'lerde 3.02 kg, 14.99 cm, 32.36 \mu , 3.53 adet ve %2.37; Akkaraman melezlerinde (iki etçi ırkın F_1 ve G_1 leri) 2.90-3.15 kg, 10.11-12.90 cm, 27.23-28.64 \mu , 6.05-6.77 adet ve %0.43-0.87 arasında; İvesi melezlerinde 2.60-3.46 kg, 8.37-14.46 cm, 27.56-30.05 u, 5.50-7.67 adet ve %0.36-1.38 ve bütün özelliklerde genotipler arası fark önemli bulunmuştur. Kırkım sonu canlı ağırlığının kirli gömlek ağırlığı ile 0.43 (P0.001), lüle uzunluğu ile 0.09 (P0.05); kirli gömlek ağırlığının lüle uzunluğu ile 0.29 (P0.001); lüle uzunluğunun elyaf çapı, ondulasyon sayısı ve kemp oranı ile 0.28, -0.42 ve 0.25 (P0.001); elyaf çapının ondulasyon sayısı ve kemp oranı ile -0.27 ve 0.35 (P0.001); ondulasyon sayısının kemp oranı ile -0.22'lik (P0.001) korrelasyonları önemli, diğer korrelasyonlar önemsiz bulunmuştur. Sonuç olarak, İvesi F1 melezlerinin yapağı verim ve kalitesinin İvesi'den yüksek olduğu, Akkaraman melezlerinin ise, yapağı verimi dışında Akkaraman'lardan farklı olmadığı, Alman Siyah Baş ve Hampshire Down melezlerinin birbirine benzer olduğu, F_1 ve G_1 generasyonlarının Akkaraman melezlerinde benzer, İvesi melezlerinde farklı ( F_1 ler G_1 lerden yüksek) olduğu kanaatına varılmıştır
This study was conducted to investigate the wool characteristics of Akkaraman, Awassi and their F_1 and B_1 crossbreed with German Blackheaded Mutton and Hampshire Down breeds. A total of 622 shearing records obtained from years 1995 and 1996 were used in study. The effects of genotype, age, shearing year, sex, post shearing body weight and its interactions on greasy fleece wight and wool characteristics were examined with General Linear Model. The effects of every examined factors on greasy fleece weight and staple length were significant except sex on staple length. The effects of genotype and shearing year on fibre diamater were significant. The effects of genotype, sex and shearing year on fibre twine were significant. The averages of greasy fleece weight, staple length, fibre diamater, fibre twine and kemp ratio were, 2.31 kg, 12.16 cm, 29.19 \mu , 5.44 units and. 1.30% respectively for Akkaraman; 3.02 kg, 14.99 cm, 32.36 \mu , 3.53 units and 2.37% for Awassi; 2.90-3.15 kg, 10.11-12.90 cm, 27.23-28.64 \mu , 6.05-6.77 units and 0.43-0.87% for F_1 and B_1 crossbreds of Akkaraman; 2.60-3.46 kg, 8.37-14.46 cm, 27.56-30.05 \i, 5.50-7.67 units and 0.36-1.38% for F_1 and B_1 crossbreds of Awassi; and the differences between genotypes were statistically significant. In the population, generally, the correlation between post shearing live weight and greasy fleece weight, and staple length 0.43 (P<0.001) and 0.09 (P<0.05) respectively. And between greasy fleece weight and staple length and fibre diamater were 0.29 (P<0.001) and 0.09 (P<0.05); between staple length, fibre diamater, fibre twine and kemp ratio 0.28, -0.42 and 0.25 (PO.001); between fibre diamater and fibre twine and kemp ratio were -0.27 and 0.35 (P<0.001) respectively. Between fibre twine and kemp ratio were -0.22 (P<0.001). The other correlations were not statistically significant. As a result, while the wool yield and characteristics of F, crossbreds of Awassi were higher than Awassi purebred, those of Akkaraman's were not higer than Akkaraman. The differences between GBM an HD crossbreds in each ew? line were not significant. And the differences between, F_1 and B_1 crossbreds were significant in Awassi line ( F_! higer than B_1) but were not in Akkaraman line. The wool yield and characteristics of crossbreds were good quality, and maybe suitable to use for blanket and flannel industry.
