Samp. is an important broad-leaved tree spread in the Mediterranean basin. In Spain few studies on the genetic variability of this species have been displayed. Storage seed proteins are a useful tool in the evaluation of the genetic variability of many species. The objective of this study was to analyze the usefulness of cotyledon proteins as markers of the genetic diversity in sweet holm oak. The evaluated populations were highly polymorphic for the glutelins being detected up to 32 polymorphic bands with a wide distribution among all them. Considering all evaluated populations about of the total allelic variation was distributed among populations. This method of analysis of cotyledon storage proteins glutelins could be considered an additional tool for the evaluation of genetic diversity in this species. Keywords seed storage proteins genetic resources sweet holm oak Storage seed proteins have proved to be a useful tool to evaluate genetic variability in many species Gepts 1990 and have been used as an important genetic marker in some species mainly in cereals in which their variability is related to technological properties of the flour Wrigley et al. 2006 . The main advantages of these proteins as markers are the high polymorphism level simple genetic control environmental independence and the economy easiness and expeditiousness of their analysis. Although the role of these proteins in forest species has been scarcely studied a few works
