Formation of core set in Indian and African finger millet [Eleusine coracana (L.) Gaertn] germplasm accessions

Published on

An investigation was made to develop a core set from the
base germplasm involving 1000 accessions of Finger
millet [Eleusine coracana (L.) Gaertn] using different
morpho-agronomic data on 11 quantitative and 12
qualitative characters. A core set of 77 accessions were
selected using the software Power core (v. 1.0). Regarding
geographical distribution of germplasm accessions in core
set, same trend was observed as in case of base
germplasm. The mean, range, variances, frequency
distribution, Shannon-Weaver diversity index and
phenotypic correlation values of core set and base
germplasm did not differ significantly indicating that the
core set represents the base germplasm and the entire
diversity has been captured in the core set. The correlation
analysis revealed that the association among yield and
yield attributing characters found in base germplasm were
also found in core set. The characters viz., plant height,
finger length, number of productive tillers per plant, days
to 50 per cent flowering, days to maturity and ear weight
per plant could be used as indirect selection for high grain
yield in finger millet.
