In the last few years, wheat production in our country has been reduced to the level of national consumption, but it is still subject to quantitative and qualitative changes. In order to under stand fluctuations in wheat production at the regional level, wheat cultivars were grown in the same locations for three consecutive years and analyzed for qualitative characteristics affecting grain utilization level during milling. The results of the paper showed that the harvest year 1997 was typical for all the cultivars and had the lowest average test weight (77.4 kg hl-1), largest absolute mass (37.9 g), highest protein content (12.5 %) and the best Flour yield (I1) (69.0%). Over the three-year period, I1 varied from 62.1 to 69.0 % over all and between 65.2 and 66.7 % in select locations. The findings of our study are a result of combined cultivar x location and cultivar x year effects, in other words, of cultivar x environment interactions. Generally, the cultivar x environment interactions in this paper were signifi cant (P<0.01), albeit relatively small. All of the study parameters varied highly significantly more by year than by location. [ABSTRACT FROM AUTHOR]
