Iran is considered as the most important gene pool for the almond species. Many of these species have valuable traits which could be utilized in breeding programs. In this study, vegetative, reproductive and horticultural characteristics of 40 trees of two wild almond species, Amygdalus scoparia Spach. and A. elaeagnifolia Spach., were investigated in the forest of Badjgah, Shiraz, Iran. Results showed that almost all of measured traits represent very high variation in both species. The range of vegetative characteristics in trees of A. scoparia showed wider scope than those of A. elaeagnifolia. The number of stamens, flower diameter, nut length, fruit set and kernel percentage were significantly different between the two species. There was no significant difference in the yield between the two species while certain trees had remarkable yield. On the other hand, kernel oil content was lower in A. scoparia compared to A. elaeagnifolia, but higher protein content was found in this latest species. Regarding flowering time, very early to very late flowering trees were found in both species. The variability found in the evaluated characteristics provides a potential for selection in further breeding programs.
