Sažetak
The researches of heritability and correlation among the withers height chest volume, and cannons volume have been done on 368 horses of the Lipizzaner breed in different phases in the Horse Selection Centre in Đakovo (Croatia). The data processing have been done by the method of the least squares. The largest value of heritability (h²) for the withers height has been established in the age of 6 months (0.80) and the smallest in the age of 12 months (0.49). The heritability values for the chest volume range between 0.31 and 0.68, and for the cannons volume between 0.25 and 0.58. The phenotypic correlations between properties were positive, except for the chest volume in the age of 6 months and cannons volume at birth being slightly negative (r = -0.096). The correlations between properties are more expressed with horses of the same age then for the different one.
