The relation between high- (HMW) and low-molecular (LMW) glutenins with the quality indicators - sedimentation value, valorimetric value and bread loaf of a collection of Bulgarian wheat varieties was studied.

A total of about 63% of the sedimentation value, 44% of the valorimetric value and 39% of the bread loaf was controlled by the two groups of glutenins and the crude protein.

The high- and low-molecular weight glutenins had an almost equal share in controlling the sedimentation value and the valorimetric value. The LMW glutenins had a significantly higher share in controlling bread loaf than that of HMW glutenins.

The participation of individual glutenin loci in quality control was not one-sided. It was mainly determined by genetic diversity and by the linking with the quality of the individual glutenin subunits.

The relative contribution of crude protein to the control of quality indicators during the various harvest years was highly variable, but its optimum quantity was a necessary condition for showing the positive effect of glutenin subunits on the quality of the wheat varieties.
