abstract: Pearl millet [Pennisetum glaucum (L.) R. Br.]
exhibits enormous genetic diversity in the global
germplasm collection. The pearl millet core collection
(~10% of the entire collection), with 2094
accessions, is still large for precise evaluation to
identify parents for a genetic improvement program.
A minicore collection of pearl millet comprising
238 accessions was constituted by using
data on 10 qualitative and 8 quantitative traits of
2094 core collection accessions. The hierarchical
cluster analysis of data using a phenotypic
distance matrix resulted in 136 clusters. A proportional
sampling strategy with 10% or a minimum
of one accession from each cluster was
used to form the minicore collection. The comparison
of data in the minicore and core collections
using various statistical parameters, such
as homogeneity of distribution for geographical
origin and frequency classes of qualitative traits,
means, median, within and between-accession
variances, diversity index, and phenotypic correlations,
indicated that almost the entire genetic
variation present in the core collection was captured
in the minicore collection. The possible
impact of high between- and within-accession
variability in pearl millet on maintenance of
genebank accessions is discussed. With its
greatly reduced size, the pearl millet minicore
collection can be used for precise evaluation of
traits of agronomic importance and biotic and
abiotic stresses as well as mapping with molecular
markers for identifi cation of trait-specifi c
germplasm and discovery of new genes.
