In This work, we have studied the phenotypic variability of the argan tree (Argania spinosa (L.) Skeels, Sapotaceae) with different morphological characteristics (spindle, oval, apical and spherical) in the Tamanr region of the province of Essaouira in southeast of Morocco. The study of this work was undertaken with the aim of researching in the argan forest the shape of the fruit of economically interesting argan trees, for in the end allowing to increase the industrial then commercial value of the argan tree in the world and can protect the argan trees. To carry out this work, we selected 23 different samples by their shape or coming from different altitudes of the province of regions of the city of Essaouira. The results of the study of the phenotypic variability of the argan tree allow us to conclude that the percentage of three almonds / fruits, the percentage of two almonds / fruits, the percentages of fat and protein in the almonds and the percentage of pulp / fruits are higher in fruits which they have an oval and spherical shape. On the other hand, the almond of the oval argan tree is very rich in fat (52%) (sample 22). The result of this work also shows that the percentage of almond moisture of all the sample is higher in lot E which it is approached from the sea (plateau 12 km from the sea). This work clearly shows that the argan tree of the oval or spherical shape are economically argan trees is the most interesting and the differences observed in the study of weight are not only related to the shape but also depend on the nature of the soil and altitude, longitude and distance from the sea.
