Non-Peer ReviewedSeed vigour of nine Polish canola varieties was studied in the laboratory using the controlled deterioration test and a modified germination test. Vigour ratings were correlated with field data from late May plantings at Saskatoon in 1998 - 2000. Correlation coefficients indicated that the modified germination test provided a better indication of seedling establishment and seedling growth than the controlled deterioration test. Exposure of seed lots to high temperature (45oC for 24 h) substantially reduced the vigour of AC Parkland and Reward but had little effect on the vigour of other Polish varieties
