Subclones of Velkopavlovicka variety of apricot were produced by individual selection from the clones of the first cycle of clone selection. Blossom buds confirmed large sensitivity to frost in the postdormancy period. An earlier onset of productivity was observed in the control clone LE 12/2. There was not any significant correlation between productivity, time of blossoming; fruit ripening and decline of blossom buds. The correlation coefficients ranged from r=0.15 to r=0.34. Fruit weight was in highly significant correlation with fruit height, width and thickness, as well as with flesh thickness and refractometric dry matter content. The values of correlation coefficients ranged from r=0.48 to r=0.82. Stone weight was in a highly significant correlation with stone width and thickness and stone percentage out of fruit weight. The value of correlation coefficients ranged from r=0.41 to r=0.73. The growth of subclones produced from less vigorous clones was slower than that of subclones coming from more vigorously growing clones.
