differences between clones with extreme values, while most other clones did not differ significantly (Tukey Kramer test). Overall adverse environmental conditions in 2011 (insufficient amount of winter chilling, excessive temperatures and drought in the spring) resulted in lower average fruit set then in 2010, when all of these conditions were more favourable (Table 3). The values ​​of fruit set for 2010 and 2011 were in line with other research, or better, which indicates a satisfactory yield potential of these clones in case of favourable weather conditions, presence of pollinators and pest control. We found statistically significant correlation between Number of flowers per 100 cm and the Number of fruits per 100 cm, and between Fruit set and the Number of fruit per 100 cm for 2010 and 2011. In this study we found no statistically significant correlation between the vegetative growth of the diameter of the whole plant and reproductive characteristics estimated using exemplary branch (Table 3).
