Abstract

In this study, the realized heritabilities with the effect of selection on 5 weeks body weight of Japanese quail line between 7 th and 15 th generations were calculated with two different methods. The effect of selection for the fifth week body weight on fertility was investigated by using path coefficient in the same subgroups of Japanese quail lines. The estimated heritabilites in females were 0.05 and 0.09 ± 0.02. The estimated heritabilites in males were 0.03 and 0.06 ± 0.02. The results showed that the antagonistic correlation between the body weight and fitness was not significant. The effects of direct and indirect factors on the number of offspring were also determined in significant

Özet

Bu çalışmada, Japon bıldırcınlarında 7 ile 15. generasyonlar arasında 5. hafta canlı ağırlık artışı yönünde yapılan seleksiyonla gerçekleşen kalıtım dereceleri hesaplanmış ve ayrıca beşinci hafta canlı ağırlık artışı yönünde yapılan seleksiyonun döl verimine etkileri iz (path) analizi ile araştırılmıştır. Canlı ağırlık artışı yönünde gerçekleşen kalıtım dereceleri dişilerde 0.05 ve 0.09±0.02, erkeklerde ise 0.03 ve 0.06±0.02 olarak tahmin edilmiştir. Canlı ağırlık artışı ile fitnes arasında istatistik olarak önemli antogonistik bir ilişki tespit edilmemiştir. Ayrıca fitnes üzerine etki ettiği varsayılan unsurların doğrudan ve dolaylı etkileri de istatistik olarak önemli bulunmamıştır
