Wild grapevine (Vitis vinifera L. ssp. sylvestris (Gmelin) Hegi) is one of the most ancient and disseminated species in the riverbanks, forests and villages of the Northern Albania. An ampelographic and ampelometric study of the mature leaf characters was carried out during 2009-2013 in three wild grapevines populations, located in three river basins. Individuals of the wild grapevines populations belongig to the Mati River Valley, the lower part of Drini Valley and Shkreli Valley, were compared by means of mature leaf characters, using IPGRI, OIV and UPOV ampelographic methods. There was found that from twentseven observed, measured and evaluated mature leaf characters, fifteen of them did not show any significant differences between three wild grapevine populations, while for twelve characters, such as size of blade (length of N1 and length of petiole), number of lobes, length of tooth N2, ratio length/width of tooth N2, and leaf angle between N1 and N3 showed significant differences. The highest value for the size of blade was measured in Drini Valley wild grapevine population, followed by Mati Valley population, while Shkreli Valley wild population showed the lowest size of blade. The same results were observed for length of tooth N2 and the ratio length/width of tooth N2. There was observed an inverse correlation between the size of blade and the angle between N1 and N3 measured at the first ramification. The highest value for angle (a + b) was measured for Shkreli Valley, while the lowest value was measured for Drini Valley wild grapevine population.
