A total of 38 male pheasants sire hatched from the second or to third incubation were measured in three breeding farms. The results showed that the diameter of the tarsus and the lenght of the remiges were characterized by very high heritability, the live weight and the body conformation index were characterised by high heritability and the take off angle was characterzed by medium-high heritability. Genetic positive correlations were observed between sire tarsus-metatarsus diameter, and sire live weight and offspring take off angle. Genetic negative correlations were observed between: sire live weight and offspring body conformation index, sire body conformation index and offspring tarsus-matatarsus diameter, sire body conformation index and offspring take off angle and sire tarsus-metatarsus diameter and offspring body conformation index.

Abstract
A total of 38 male pheasants sire hatched from the second or to third incubation were measured in three breeding farms. The results showed that the diameter of the tarsus and the lenght of the remiges were characterized by very high heritability, the live weight and the body conformation index were characterised by high heritability and the take off angle was characterzed by medium-high heritability. Genetic positive correlations were observed between sire tarsus-metatarsus diameter, and sire live weight and offspring take off angle. Genetic negative correlations were observed between: sire live weight and offspring body conformation index, sire body conformation index and offspring tarsus-matatarsus diameter, sire body conformation index and offspring take off angle and sire tarsus-metatarsus diameter and offspring body conformation index.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
