Description Finger millet [Eleusine coracana (L.) Gaertn.],
among small millets, is the most important
food crop in some parts of Asia and Africa. The
grains are a rich source of protein, fi ber, minerals,
and vitamins. A core collection of 622
accessions was developed. The aim of this
study was to develop a mini-core collection
using multilocational evaluation data of the core
collection. Six hundred and twenty-two accessions
together with six controls (four common
and two location-specifi c) were evaluated for 20
morphological descriptors at fi ve agroecologically
diverse locations in India during the 2008
rainy season. The experiment was conducted
in α design with two replications at Patancheru
and in augmented design with one of the six
controls repeated after every nine-test entry at
other locations. The hierarchical cluster analysis
of data using phenotypic distances resulted
in 40 clusters. From each cluster, ~10% or a
minimum of 1 accession was selected to form
a mini-core, which was comprised of 80 accessions.
The comparison of means, variances, frequency
distribution, Shannon–Weaver diversity
index (H`), and phenotypic correlations revealed
that the mini-core captured the entire diversity
of the core collection. This mini-core collection
is an ideal pool of diverse germplasm for identifying
new sources of variation and enhancing
the genetic potential of fi nger millet.
