Based on observations and established results related to reproduction characteristics, i.e. physical and incubation values of the Italian White Goose, following conclusions were drawn: out of 400 incubated eggs, 352 were fertilised (88.00%); 316 goslings were hatched (79% and 89.77% out of the number of inlaid and the number of fertilised eggs respectively); while the mortality during the incubation period (early, medium and late) amounted to 36 dead embryos (9.00% and 11.39% out of the number of incubated and the number of fertilised eggs respectively). Furthermore, following correlation was established by calculating the coefficients of phenotype correlation between major traits: very weak – between egg weight and egg shape index (rp = 0.180**); absolute – between egg weight and hatching weight of goslings (rp = 0.986***); medium – between egg weight and gosling percentage in the egg weight (rp = 0.477***); weak – between egg shape index and gosling weight (rp = 0.195***); while between the egg shape index and the gosling percentage in the egg weight no statistically significant (P>0.05) correlation was established (rp = 0.031NS).
