In order to deal with world collect~ono f pearl m~lleta nd its elTectivc otiliz~tion,1 11s estahlisliment of a core collection is one ofthe ideal appn~nche. I:urthcr, an assessnicnt 111' genetic diversity based on morpho-agronomic cliaracrers only m~ght be biased hccause distinct niorphotypes can result from a few mutations and share a comnion genetic background. Therefore, molecular markers are essential for explaining whether existing genetic variability, assessed by measuring morpl~o-agronomic characters, is related to genetic diversity. This may be assessed by measuring allelic frequencies using molecular markers. Thus, the present study was undertaken with an objective to establish a pearl millet core collection that represents a complete range of genetic diversity of the world collection and to achieve the following objectives: To compare multivariate vs. hierarchical classification for determining core collections that maximizes diversity. To evaluate the adequacy of mean characterization data to determine core collection and do diversity assessment in a cross-pollinated crop. To determine the extent of diversity within and between accessions of established core collection using morphological traits and molecular markers.
