Abstract: 

In order to evaluate seed vigour tests on emergence three common wheat cultivars Mahdavi, Qods and Roshan an experiment as randomized complete block design with three replication was conducted during 2006-2007 in laboratory, to study of germination standard test, first count test, seedling growth rate, Staining index tetrazolium tests and electrical conductivity. And also a field work as randomized complete block design with three replications was done at experimental station of agricultural collage of Islamic Azad University Dameghan to study percentage and speed of seedling emergence Roshan and Mahdavi and Qods cultivars had lower and higher percentage and speed of seedling emergence, respectively. There was significant positive correlation between seed vigour tests, percentage and speed of seedling emergence.
Among the seed vigour tests, first count, seedling growth rate (dry matter accumulation) and staining index tetrazolium tests had the highest correlation with percentage and speed of seedling emergence.
So these tests are recognized as the best tests to evaluate seed vigour.
