| Abstract: | Background The distribution area of pearl millet in West and Central Africa (WCA) harbours a wide range of climatic and environmental
conditions as well as diverse farmer preferences and pearl millet utilization habits which have the potential to lead to local
adaptation and thereby to population structure. The objectives of our research were to (i) assess the geographical distribution
of genetic diversity in pearl millet inbreds derived from landraces, (ii) assess the population structure of pearl millet
from WCA, and (iii) identify those geographical parameters and environmental factors from the location at which landraces
were sampled, as well as those phenotypic traits that may have affected or led to this population structure. Our study was
based on a set of 145 inbred lines derived from 122 different pearl millet landraces from WCA. |
