Inheritance of egg quality traits in selected and control lines of japanese quail

Body weight and egg quality traits of 232 females, progeny of 35 sires belonged to selected and control line of Japanese quails, were recorded up to 16 weeks of age. Selected line were significantly (P<0.01) heavier than control line at 16 weeks of age. The selected line had higher egg weights, yolk weight and albumin weight as compared to control line. The heritability estimates, pooled over the both lines were high for body weight, albumin weight and shell weight (0.51 to 0.87), moderate for egg weight, yolk weight and % shell weight (0.26 to 0.35) and low for % yolk weight, % albumin weight and specific gravity (0.11 to 0.24).
