The experiment was carried out at DAOUDI Larbi pilot farm in El Harrouch, during the 2021/2022 crop year, under sub-humid weather conditions. The main objective of this research is based on the study of production and adaptation characters of seven durum wheat newly obtained genotypes (Triticum durum Desf.). The results of descriptive sheets according to UPOV recommendations (2014-2017), showed diversity between the varieties studied, such as: plant height, straw section, awns (presence, disposition, anthocyanin pigmentation, color, and length), ear (density, color, shape, length and glaucescence), lower glume (shape, color, weight and shape of shoulder, length and curvature of beak), neck glaucescence, length of rachis… According to the results obtained of production and adaptation characters we find that Numidia presented the high value of number of Plant/m2 (350 ± 4.58), Emilio Lepido showed a high level of Number of Herbaceous tillers/Plant (2.70 ± 0.52), number of Grains/Ear (37.1 ± 6.85), and Harvest index (35.62 Qunitals/Acres). While, the number of Ears tillering/Plant, number of Ears/m2, thousand grains weight, grain yield, biomass aerial, and economic yield (1.67 ± 0.31, 423.33 ± 15.95, 48.6 g, 62.13 ± 2.34 Qunitals/Acres, 184.6 ± 1.7 Qunitals/Acres and 98.88 ± 2.01 Qunitals/Acres). According to the results obtained the Shannon and Weaver relative diversity index showed a low diversity in all accessions studied (H’Mean=0.41). Finally, we concluded that the creation of descriptive sheets, the knowledge of production and adaptation parameters are considered as precursors of high yield, they allow us to better exploit these species according to economic needs, agro-ecological conditions, and mastery of production techniques in improvement programs.
