The millet is one of the most important cereals for food and feed in the world. Through this study, the behavior of 15 autochthonous cultivars of pearl millet in presence of one Nigerian control was done in Mitidja’s conditions (sub-humid region in Algeria) to assess the variability using pheno-agro-morphological traits, grain and panicle quality. Analysis of variance showed the existence of a large variability between landraces, revealed by very highly significant differences among the following characters: plant height, panicle length, panicle thickness, 1000 grain weight and crude fiber content of panicles. Differences were significant for stem diameter and panicle weight and high significant for dry matter content of panicles. Principal component analysis showed that four components explained 81.03 % of variation. The greatest variability was explained by the following traits: panicle weight, panicle length, panicle thickness, 1000 grain weight and crude fiber content of panicles. Significant correlations existed between many traits studied which are promising for breeding works.
