%X regularly, quality analyses of argentine wheat production are performed in order to know its industrial quality. these analyses are insufficient to compare effects of cultivar, location, year and their interactions. the aim of this work is to quantify the effects of these factors. eight cultivars were grown in four argentine locations during three cropping seasons. ten quality traits were evaluated: mean weight of grain, hectolitric weight, flour yield, wet gluten, dry gluten, gluten index, protein concentration, alveographic variables, water absorption, bread volume. a wheat quality index was calculated and quality groups were established. coefficient of variation was calculated in order to compare the effect of each factor. for most variables studied, significant differences for each factor (p=0.05) were found .the location and year effects on quality traits were so important or more so than the cultivar effect. the most important interaction effect was location x year. the classification in quality groups was affected by location. thus, location inclusion in wheat classification would be justified to define production protocols and to classify cultivars and argentine wheat production.
