摘要：<正> Wheat processing quality is greatly influenced by the seed proteins especially the high molecular weight glutenin subunit (HMW-GS) components, the low molecular weight glutenin subunit (LMW-GS) components and gliadin components. Genes encoding the HMW-GS and LMW-GS components were located on the long arms and the short arms of homoeologous group 1 chromosomes, respectively. HMW-GS components in 5 129 accessions of wheat germplasms were analyzed systematically, including 3 459 landraces and 1 670 modern varieties. These accessions were chosen as candidate core collections to represent the genetic diversity of Chinese common wheat ( Triticum aestivum) germplasms documented and conserved in the National Gene Bank. These candidate core collections covered the 10 wheat production regions in China. In the whole country, the dominating alleles at the three loci are Glu-A1b (null), Glu-B1b (7 + 8), and Glu-D1a (2 + 12), respectively. The obvious difference between the land race and the modern variety is the dra
