Description Viability and vigour are seed quality parameters that affect the seed chain. Seed vigour is a measure of
accumulated damage in seed as viability declines from physiological maturity. This study aimed at
determining the seed vigour of various sorghum genotypes stored ex situ for 10 years using the Heat
Shock Stress Test (HSST), Cold Test (CT), Standard Germination Test (SGT) and field germination. The
samples from the regeneration trial were kept in ex situ storage at 0-4°C and 40% relative humidity from
2003 to 2014. The experiments were arranged in a completely randomised design with four replication
and differences in radicle length, shoot length for the 65 genotypes evaluated at 5% level of
significance. An unpaired T- test was used to compare the accuracy of the quality methods in
predicting field emergence. All the evaluated genotypes responded differentially to all the vigour test
methods. There were significant differences (P
