The starches were isolated by alkaline extraction from white and red sorghum, predominant cultivars in the Sahara of Algeria. Morphological, thermal properties and amylose content of isolated starches were examined. The starches of two sorghum landraces of white and pigmented kernels growing in hyper arid environmental conditions showed significant differences in granule size, amylose content and thermal behavior which ultimately affect the physicochemical and functional properties. When observed using environmental scanning electron microscopy （ESEM）. The starch granules showed polyhedral shape. Some of them showed pinholes. The granular size ranged between 6.325-39.905 μm and 7.096-44.774 μm, respectively for white and red sorghum starches. The granule size distribution was unimodal. The amylose content in white sorghum starch （27.1%） was higher than that in red sorghum （24.8%）. Differential scanning calorimetry （DSC） analysis revealed that sorghum starches present higher temperatures at the peak （70.60℃ and 72.28℃ for white and red sorghum starches, respectively） and lower gelatinization enthalpies （9.087 J/g and 8.270 J/g for white and red sorghum starches, respectively） than other cereal starches. The determination of these properties is relevant to the comprehension of starch and starch-based foods digestibility in order to direct them towards the specific applications in food and nonfood sectors.

Despite the areas restriction reserved for pearl millet cultivation in Hoggar region, there is an important diversity, which has occupied an essential place in the inhabitants’ diet. For a better knowledge of its biodiversity, seven sites were prospected during the plant maturation period. The morphological and cytological study was undertaken on the basis of the descriptors parameters of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). The most widely varied variables were the Height of the Plant (HP), Stem Diameter (ST), Panicle size;Length (PL), Width (PW) and Color (PC). While very low variation was noted in 3rd leave dimensions;Leaf Length (LL), Leaf Width (LW), Number of Nodes (NN) and Seed Form (SF). Therefore, local millet (***, MLH.Z1) and some domesticated (MDH. Saf, MDH.S) appeared as the best groups, based on their panicle characters and seed nutritional quality. Agro-morphological changes detected in this study, show that the majority of millet domesticated (MDH. Saf. P, MDH. Sepl) are generally, classified in second place and used as fodder in the Hoggar region.
