The paper shows the results of the genetic potential of some peach cultivars (Prunus persica L.) used as genitors in the breeding process. A detailed morphological and structural description of pollen grains of four peach cultivars 'Raluca’, 'Florin’, 'Filip’ and 'Monica’ was done. The pollen was collected from peach flowers in April from the demostrative plots at Research Station for Fruit Growing Constanta (RSFG Constanta). The viability and pollinated tube cultures were made in order to determine the fertility and germination capacity of the analyzed biological material. The one with the highest viability of the pollen grains was recorded at 'Raluca’. 'Florin’ cv. has been shown the highest germination capacity on a 15% sucrose nutrient medium after a 2 hour sprouting time (89.6%), followed by a 5% sucrose nutrient medium with after 2 hours of germination time (88.9%).
