Abstract :Pollen is an important morphological parameter for cultivar identification. This is of great importance in detailed investigations by scanning electron microscope insert ignore into journalissuearticles values(SEM);. In this study, the pollen morphology of selected grape cultivars was examined by SEM. The pollen length, width, P/E ratio of pollen and features of surface were observed. The pollen differed in some microstructural characteristic. Pollen width exhibited significant according to the varieties insert ignore into journalissuearticles values(10.12-22.44 μm);. Similarly, the statistical difference occurred among the thirty Vitis cultivars in terms of mean pollen length insert ignore into journalissuearticles values(16.26-29.65 μm);. Areolat pollen was determined in some cultivars. Depending on the cultivars there was significant differences in terms of pores diameter. According to PCA performed in 30 grape cultivars, 3 principal components were revealed and they defined 94.98% of the variance. Cultivars were divided into groups according to pollen features on the cluster. Consequently, the cultivars were categorized under two main groups. The present research is a contribution to a more detailed analysis of grapevine cultivars.
