Description A study was undertaken to assess and analyze the seed
viability data of 36,483 sorghum germplasm accessions
conserved as active collection at ICRISAT genebank,
Patancheru, India. The viability tests were conducted for
seven years. The period of storage was less for freshly
regenerated accessions while for majority of the
accessions (35,221) it ranged between 5 and 21 years.
The seed viability of 34,894 accessions (95.6% of the
total tested accessions) was >85%, a minimum standard
for orthodox seeds for conservation as active collection
in international genebanks. This exercise has resulted in
identifying several important areas like basic and
intermediate races of sorghum, seed covering structures,
the nature of endosperm, etc, critical for improving the
operational procedures and protocols for the management
of the ex-situ sorghum germplasm collection.
