The HEALTHGRAIN program is focused on developing new healthy food products based on wholegrains of wheat and other cereals, by combining enhanced nutritional quality with good agronomic performance and processing quality. A sample set comprising 130 winter and 20 spring wheat varieties was therefore selected to identify the range of variation in a number of phytochemical and dietary fiber components. These lines were also analyzed for their technological properties (protein and gluten contents, Zeleny sedimentation, bran yield, kernel hardness, etc.), using samples grown on adjacent sites for two successive seasons (2004−2005, 2005−2006). On the basis of the frequency distribution and principal component analysis it was concluded that significant variation for technological quality traits is present in the 150 wheat lines and that it is possible to combine enhanced nutritional quality with good agronomic performance and processing properties.
