"Viability and vigour are seed quality parameters that affect the seed chain. Seed vigour is a measure of\r\naccumulated damage in seed as viability declines from physiological maturity. This study aimed at\r\ndetermining the seed vigour of various sorghum genotypes stored ex situ for 10 years using the Heat\r\nShock Stress Test (HSST), Cold Test (CT), Standard Germination Test (SGT) and field germination. The\r\nsamples from the regeneration trial were kept in ex situ storage at 0-4°C and 40% relative humidity from\r\n2003 to 2014. The experiments were arranged in a completely randomised design with four replication\r\nand differences in radicle length, shoot length for the 65 genotypes evaluated at 5% level of\r\nsignificance. An unpaired T- test was used to compare the accuracy of the quality methods in\r\npredicting field emergence. All the evaluated genotypes responded differentially to all the vigour test\r\nmethods. There were significant differences (P<0.01) in the performance of genotypes with respect to\r\nradical and shoot length in response to the CT, HSST and the SGT. The results of CT and HSST\r\npredicted field emergence better than the standard germination test. None of the quality test methods\r\nand a strong and significant correlation with field emergence. Genotypes IS 30260 and IS 34637 were\r\nvigourous as they had the highest shoot length of 43.75 and 42.38 mm and IS 30063 had 45.52 mm in\r\nroot length after 48 h of incubation. Overall, this study showed that field emergence of sorghum cannot\r\nbe accurately predicted from a standard germination, HSST and CT."^^ . "2015" . . "6" . "6" . . "Academic Journals"^^ . . .
