TL;DR: A significantly lower number of alleles and lower gene diversity in cultivated pearl millet accessions than in wild accessions is shown, which contrasts with a previous study using iso-enzyme markers showing similar genetic diversity between cultivated and wild pearl Millet populations.

TL;DR: Multivariate analyses showed the specificity of the subrace guinea margaritiferum, as well as the geographical and racial pattern of genetic diversity in cultivated sorghums, which aid in the optimization of sampling accessions for introgression in breeding programs.

TL;DR: A large diversity survey in sorghum with 3367 accessions and 41 reference nuclear SSR markers is presented and a core reference set is proposed in order to facilitate integrated phenotyping experiments towards refined functional understanding of Sorghum diversity.

TL;DR: No erosion of varietal diversity was noted on a national scale during the period covered and this highlights that farmers’ management can preserve the diversity of millet and sorghum varieties in Niger despite recurrent and severe drought periods and major social changes.

TL;DR: The geographical situation of Niger, where typical western African, central African and eastern Sahelian African sorghum races converge, explained the high observed genetic diversity and was responsible for the interactions among the ethnic, geographical and botanical structure revealed in this study.
