Genetic Differentiation for Gene Diversity among Pearl Millet (Pennisetum glaucum (L.) R. Br.) Landraces As Revealed by SSR Markers

Pearl millet (Pennisetum glaucum) is one the most important crops in Burkina Faso. Knowledge of the genetic parameters of different pearl millet landraces grown in Burkina Faso is of great importance for improvement and breeding programs of pearl millet. In this study, 20 pairs of SSR markers were u...
