Journal ArticleDOI
Diversity of wild and cultivated pearl millet accessions (Pennisetum glaucum [L.] R. Br.) in Niger assessed by microsatellite markers
Cédric Mariac,Viviane Luong,Issoufou Kapran,Aïssata Mamadou,Fabrice Sagnard,Monique Deu,Jacques Chantereau,Bruno Gérard,Jupiter Ndjeunga,Gilles Bezançon,Jean Louis Pham,Yves Vigouroux +11 more
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.
Journal ArticleDOI
Changes in the diversity and geographic distribution of cultivated millet ( Pennisetum glaucum (L.) R. Br.) and sorghum ( Sorghum bicolor (L.) Moench) varieties in Niger between 1976 and 2003
Gilles Bezançon,Jean Louis Pham,Monique Deu,Yves Vigouroux,Fabrice Sagnard,Fabrice Sagnard,Cédric Mariac,Issoufou Kapran,Aïssata Mamadou,Bruno Gérard,Jupiter Ndjeunga,Jacques Chantereau +11 more
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.
Journal ArticleDOI
Niger-wide assessment of in situ sorghum genetic diversity with microsatellite markers.

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.
Journal ArticleDOI
Genetic structure among sorghum landraces as revealed by morphological variation and microsatellite markers in three agroclimatic regions of Burkina Faso
Clarisse Pulchérie Barro-Kondombo,Fabrice Sagnard,Fabrice Sagnard,Jacques Chantereau,Monique Deu,Kirsten Vom Brocke,Patrick Durand,Eric Gozé,J. D. Zongo +8 more
TL;DR: Cluster analysis revealed that the diversity was weakly stratified and could not be explained by any biophysical criteria, and one homogenous guinea margaritiferum group was distinguished from other guinea landraces.
Journal ArticleDOI
Genetic structure and relationships within and between cultivated and wild sorghum (Sorghum bicolor (L.) Moench) in Kenya as revealed by microsatellite markers
Evans Mutegi,Fabrice Sagnard,Kassa Semagn,Monique Deu,Moses M. Muraya,Ben M. Kanyenji,S. de Villiers,Dan Kiambi,Liezel Herselman,Maryke Labuschagne +9 more
TL;DR: In both cultivated and wild sorghum, genetic diversity was found to be structured more along geographical level than agro-climatic level, which indicated that gene flow and genetic drift contributed to shaping the contemporary genetic structure in the two congeners.
