It was discovered that sedimentation values of samples from differentreg-ions tended to increase more both from the south to the north and from plain to plateau.

The correlation between the SDS- sedimentation value and Zeleny - sedimentation value of spring wheat grain was significantly positive (r_20min=0.

The grain proteins of F 3 progenies from 2 crosses and 14 China-grown wheat varieties were fractionated by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) to determine their HMW glutenin subunits and their relation to SDS sedimentation value.

In this research,36 wheat cultivars grown in Shan xi were employed to determine the HMW glutein subunit compositions and SDS sedimentation volume,which the main objectives might analyze the relationship between HMW-GS composition and SDS sedimentation volume for the bread-making quality of wheat.

advance wheat lines, obtained from a wide cross between wheat and rye inbred lines, were studied on correlation between HMW-GS, protein components and quality characteristics including SDS sedimentation volume and Glu-1 quality score.

In order to evaluate if the quality test method of SIG(Swelling Index of Glutenin) was applicable in wheat breeding program for quality plants screening,various wheat flours,blended flours and whole-meals from different varieties or lines were tested by means of Zeleny sedimentation value,SDS sedimentation value and SIG,and the correlations among the three parameters were analyzed.
