The main purpo se of the experiment was to investigate the influence of cultivation conditions of mother and daughter plants on the number and size of strawberry plug plants. The experiment was conducted inside and outside of a high plastic tunnel. Cold stored mother pla nts of ‘Dukat’ and ‘Camarosa’ were planted in containers containing four types of substrate: peat substrate + sand, peat substrate + perlite, peat substrate + compost soil, and compost soil. The results revealed that the place of cultivation of mother plan ts and plug plants (daughter plants) influenced the size of strawberry plug plants in both cultivars. The largest plants of both cultivars were obtained when they were rooted in a mixture of peat substrate and compost soil. It was also observed that the ge notype had a big effect on the size and number of plug plants.
