The paper presents the results of genetic analysis of major pomological properties (the number of set and harvested fruits, fruit and stone weight and yield) in peach. The components of total variability and heritability coefficients in wider sense were assessed. Twenty peach cultivars and two hybrids were used as material. Genetic differences between peach cultivars mostly indiced fruit and stone weight variability, while the variations in number of fruit set, harvested fruits and yield were mostly caused by ecological factors. Relatively high values of heritability coefficient were assessed for most properties (74.05-96.04%), wheres heritability was moderate only for yield (54.84%). On the basis of the correlation coefficient value, it was determined that the yield was in highly significant or significant genetic correlation to fruit weight (0.851**) and stone weight (0.481**) and that it highly phenotypically correlated to the number of fruit set (0.576*) and fruit weight (0.556*).
