The influence of wheat sowing dates on the starch properties was evaluated during several growing seasons (2002 to 2005). Some European wheat varieties were sown at 2 distinct dates, cultivated in the same growing conditions and simultaneously harvested. The comparison of the 4 harvest seasons shows globally the same observations and the results of 2005 harvest are presented in this paper. A significant impact of the sowing date on the starch properties are measured for most of the studied

... ties. An appropriate selection of the wheat variety and its sowing date could be valorised to emphasize starch properties researched in industrial end uses. Furthermore, these variations between the starch characteristics could lead to processing or endproducts quality problems.
