| Abstract: | Background In the last hundred years, the development of improved wheat cultivars has led to the replacement of landraces and traditional
varieties by modern cultivars. This has resulted in a decline in the genetic diversity of agriculturally used wheat. However,
the diversity lost in the elite material is somewhat preserved in crop gene banks. Therefore, the gene bank accessions provide
the basis for genetic improvement of crops for specific traits and and represent rich sources of novel allelic variation. |
