Abstract

A set of quality parameters (crude protein content, Zeleny sedimentation test, wet gluten content, gluten index, albumins + globulins content, gliadin content, sum of glutenins, proportion of albumins + globulins in crude protein and relative viscosity) was tested in 17 doubled haploid (DH) wheat lines differing in the presence or absence of 1B/1R translocation. The presence of 1B/1R translocation (allele Gli 1B3) affected the significantly higher content of albumins and globulins and significantly lower value of gluten index. Nevertheless, a certain translocation influence on the other parameters (Zeleny sedimentation test; relative viscosity; proportion of albumins + globulins in crude protein) was also registered. The deteriorative effect of the 1B/1R translocation on indirect technological grain parameters was confirmed more markedly in gluten index than in Zeleny sedimentation test. A high number of significant differences between lines was found in Zeleny sedimentation test, content of glutenin, content of albumins + globulins and their proportion in crude protein. In spite of lower variability between lines relative viscosity showed a high dependence on genotype and was indifferent to the other quality parameters.
