Abstract
Wild Almond species are classified in Prunus genus and Amygdalus subgenus and 2 series of Icosandrae and Dodecandra. In the first classifications of Iranian wild almonds, their species were classified based on the thorn characteristics of branches, petiole length and leaf blade shape and size.
Wild almond species in different ecological regions poses a large variation in their leaf sizes and pubescences, which make their classification hard and sometimes impossible.
Therefore, it has been suggested that, nut characteristics should also be considered for characterization of wild almond.
The IBPGR and UPOV descriptors for classification of cultivated almonds have been used for nut shape classification in wild almonds, but it seems that it is not sufficient enough for classifying very diverse wild almond species, as there are more different types of nut shapes.
Therefore an experiment was conducted as Completely Randomized Design (CRD) to compare the nut morphological characteristics of 56 Iranian wild almond accessions.
The nut shape (7 groups), nut length, nut width, ratio of nut length/width, nut thickness, nut weight, ratio of kernel length/width, kernel thickness, kernel weight, kernel yield, kernel marking (8 groups), kernel length, and kernel width was considered.
The results of Duncan means comparison indicated that these characteristics are significant at p ≤0.01. The accessions of P. lycioides (var. horrida) and P. scoparia had the least length (8.6 mm) and the least width (6.8 mm) respectively.
