Abstract(#br)The aim of this study was to determine to what extent the measurement of wheat endosperm colour can be used to predict its hardness. The results indicate that there is no general (for all varieties) relationship between the colour of wheat endosperm and its hardness. Nevertheless, endosperm hardness tends to increase along with increasing values of b*, H and S attributes and decreasing values of a*. More promising results were obtained when the colour–hardness relationship was examined within a variety. In all cases, the results were statistically significant, but the endosperm hardnesses of Zyta, Rysa, Banti, Sakwa, and Mewa varieties were found to be more closely linked with the colour of the central part of the endosperm ( r ranging from 0.53 to 0.76), whereas that of... durum and Elena wheats were found to be more closely linked with the colour of the whole endosperm ( r =0.70 and 0.57 respectively). It was observed that the varieties examined can be divided into three groups differing in the range of changes in hardness as a function of the b* attribute of endosperm colour. For group I (durum and Zyta), the rate of hardness increase was higher than that of group II (Rysa, Banti and Sakwa). The third group (Elena and Mewa) was characterised by the highest slope of hardness versus b*; however, it was well differentiated from group I by its low values for yellow.
