Description Pearl millet [Pennisetum glaucum (L.) R. Br.] was
domesticated in Sahelian West Africa. This highly
outcrossing crop is one of the most important
staple cereals in the semiarid tropics, adapted to
very harsh rain-fed conditions. Agro-morphological
characterization of local germplasm is very
important to better understand existing diversity,
ease targeted genetic broadening of breeding
populations, and potentially link this knowledge
to genotypic information. The objectives of our
study were to (i) characterize West and Central
African (WCA) pearl millet accessions based on
their agro-morphological traits; (ii) evaluate the
possibility to group accessions based on their
agro-morphological characteristics; (iii) determine
geographic patterns of phenotypic differentiation;
and (iv) derive conclusions for pearl millet
improvement in WCA. A total of 360 early-tomedium
maturity accessions were phenotyped
for 12 agro-morphological traits at six environments
in WCA. Wide ranges of all observed traits
indicated a high diversity of the tested accessions.
Principal component analysis revealed
very large diversity within individual countries,
especially within Mali and Burkina Faso. Some
limited grouping of accessions from Niger, Senegal,
Cameroon, Morocco, and Mauritania was
observed for individual principal component
axes. Geographical differentiation and country
differences were detected for several traits. The
results and data presented in our study reflect
WCA pearl millets’ tremendous diversity and
adaptability to a wide range of environments and
give a sound basis for breeders to select and utilize
this germplasm to serve the manifold needs
of WCA pearl millet farmers.
