FFECT OF DIALLEL CROSS BETWEEN THREE VARIETIES OF JAPANESE QUAIL COTURNIX COTURNIX JAPONICA IN SOME BLOOD TRAITS

Abstract

This study was conducted in poultry farm/Department of Animal production/ College of Agriculture/University of Diyala, for the period from 3/7 to 30/10/2015. The aim was to determine the effect of diallel cross (3×3) between there varieties of Japanese Quail (Coturnix coturnix japonica),White (W), Black (B) and Brown (N) plumage color on blood traits in males and females to estimate the main effects of sire and dam, effect of interaction between sire and dam, general combining ability, specific combining ability reciprocal effect, heterosis and maternal effects. The results showed asignificant difference between sire effect of male on number of WBC to varietie Black on White and high significant effect between Black and Brown Varieties in concentration of hemoglobin and cholesterol.The main effect dam show superiority of Black Variety on White Variety on concentration of cholesterol. The effect of interaction between sire and dam in blood traits in male progeny showed significant in: number of WBC, Hemoglobin concentration and concentration of cholesterol. The general combining ability for blood traits of pure Variety in male progeny significant values in concentration of hemoglobin and cholesterol. Specific combining ability showed No significant values for all traits of blood.The reciprocal effect showed significant values for WBC and concentration of hemoglobin. The results of interaction between sire and dam in blood traits of female progeny showed significant values in number of WBC, concentration of hemoglobin and cholesterol. The general combining ability values showed no significant differences in concentration of hemoglobin, concentration of cholesterol and Packed Cell Volume. Specific combining ability showed significant values in concentration of hemoglobin. The reciprocal effect showed significant values for concentration of hemoglobin and cholesterol. The results of heterosis value of blood traits in male progeny, showed significant differences in concentration of hemoglobin. The maternal effect values showed significant differences in concentration of hemoglobin, and the result of heterosis values of blood traits in female progeny, significant differences in hemoglobin and cholesterol concentration and No significant showed differences between maternal effect of all traits in blood of female progeny.
