Although genotype has a major impact, wheat quality cannot be predicted only by selecting the cultivar. The good quality genetic potential may be reached depending on the growing conditions (Wrigley, 2007). Uruguay wheats are characterized by its suitability for direct bread making. In order to obtain this, cultivars are annually evaluated for both agronomical behavior and industrial quality. The experimental information shows an acceptable potential behavior in baking quality for all of them, although these results are not always reached in field conditions. Variables such as soil fertility, soil tillage systems, seeding date, diseases and nitrogen availability may modify cultivar behavior (Anderson et al., 1995). The objective of the present work was to understand the impact of different environments and management practices used by Uruguayan farmers on grain and flour quality variability during 6 years.
