    ABSTRACT
    This study aims to identify the Sorghum bicolor (L.) Moench (Poales Poaceae) phenotypes grown in southern of Algeria (Tidikelt region). We organized several field visits to sorghum cultivation sites during the plant’s maturity period to inventory and evaluate the phenotypes of this crop, based on the descriptive study of the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT). The results of plant parameters measurements demonstrated, that plant height (HP), the number of nodes (NN) and leaves (LN), and panicle color (PC) showed significant differences, while we recorded very slight differences for the dimensions of the third leaf: Length (L.3L) width (W.3L) and panicle (PL and PW). The results also showed that there is a phenotypic diversity of local white and red sorghum, in addition to mixed and domesticated sorghum, which are commonly used as fodder. On this basis, this type of cereal cultivation can play a leading role in promoting the cultivation of millet groups local to the region.

    Biodiversity of pearl millet Pennisetum glaucum (L) R. Br. (Poales Poaceae) in southern Algeria (Tidikelt region)

    ABSTRACT
    The study aims to identify the Pennisetum glaucum (L) R. Br. (Poales Poaceae) phenotypes cultivated in Tidikelt region. We conducted field visits during the plant maturity stage, to evaluate these patterns, based on the descriptive study of the International Crop Research Institute for the Semi-Arid Tropics. The results showed significant differences between plant height, the number of nodes and leaves, seed color, and main stem length. Whereas, we recorded only slight differences for the dimensions of the third upper leaf and panicle. It was also found that the best groups of locally cultivated millet were pearly and yellow millet, due to the morphological characteristics of their panicles, unlike wild millet (MLT.VN, MLT.VNP) and domesticated (MDT.Sepl, MDT.Sepc, and MDT.Smix) which are used as feed. On this basis, this type of cereal culture could play a leading role in promoting the cultivation of local millet groups in this region.
