Abstract: In order to understand the background and utility value for purple or blue grain wheat,the glutenin and gliadin of 9 purple or blue grain wheat are analyzed by the method of polyacrylamide gel electrophoresis (PAGE).The high molecular weight glutenin subunits (HMW-GS) results from sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) showed that there were 8 types of subunits and 6 types of subunit combination in 9 materials.Subunit 1 (66.7%),7+8 (55.6%) and 5+10 (55.6%) were the majority subunit in Glu-A1, Glu-B1 and Glu-D1 loci,respectively.Subunit combination 1/7+8/5+10 and Null/7+8/5+10 were the mainly type in materials.In low molecular weight glutenin subunits (LMW-GS),there are 7 (41.2%) bands showing in all materials which isolating totally 17 bands.The gliadin results from acid polyacrylamide gel electrophoresis (A-PAGE) showed that there are 7 (35.0%) bands showing in all materials which isolating totally 20 bands.The clustering analysis based on the bands from LMW-GS and gliadin indicated that the genetic distance of the materials is from 0.07 to 0.37.These 9 materials can be divided into four categories at the level of 0.22.Materials HR-1 and NH-1 can be gathered at the value of 0.07.Purple grain wheat Luozhen 1,HR-1 and NH-1 can be used in breeding and genetics programs for variety improvement because of its good agronomic traits and quality subunits 1 and 5+10.
