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.
Monique Deu,Fabrice Sagnard,Jacques Chantereau,Caroline Calatayud,Damien Herault,Cédric Mariac,Jean Louis Pham,Yves Vigouroux,Issoufou Kapran,Pierre C. Sibiry Traoré,Aïssata Mamadou,Bruno Gérard,Jupiter Ndjeunga,Gilles Bezançon +13 more
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
Spatio-temporal dynamics of genetic diversity in Sorghum bicolor in Niger
Monique Deu,Fabrice Sagnard,Jacques Chantereau,Caroline Calatayud,Yves Vigouroux,Jean Louis Pham,Cédric Mariac,Issoufou Kapran,Aïssata Mamadou,Bruno Gérard,Jupiter Ndjeunga,Gilles Bezançon +11 more
TL;DR: Results suggest that farmers’ management has globally preserved sorghum genetic diversity in Niger, which was submitted to recurrent drought period and to major social changes during these last decades.
Journal ArticleDOI
Population genomics of sorghum (Sorghum bicolor) across diverse agroclimatic zones of Niger.
Fanna Maina,Fanna Maina,Sophie Bouchet,Sandeep R. Marla,Zhenbin Hu,Jianan Wang,Aïssata Mamadou,Magagi Abdou,Abdoul-Aziz Saidou,Geoffrey P. Morris +9 more
TL;DR: The genomic diversity of sorghum from Niger is characterized and genomic regions conferring local adaptation to agroclimatic zones and farmer preferences are identified, which could facilitate genomics-assisted breeding of locally adapted and farmer-preferred Sorghum varieties for Niger.
