The study was carried out in Date Palm Research Center Laboratory and College of Agriculture – Basrah University to compare protein electrophrestic patterns for three cultivars of date palm selected for the experiments. Young leaflets were taken from three different cultivars (Ghennamy Al-Akhdar, Samasmi, Khikri) grown in shatt –Al arab - Alfaiha- Iraq. Electrophresis studies showed differences in protein pattern and dinsty and molecular weights. The results indicted that there were differences between proteins in both types and quantities in all three pollen cultivars. Also the results showed that three male cultivars contained one common pand in the same location that has low molecular weight. Al so, results showed the process of differential gen expression has accorded since there were bands, which differed in number. position, and density on the gel in particular male cultivar. There were very distinct differences between of the three male type.
