Ten advanced wheat germplasms, named Chunjie 1, 2, 3, 4, 5 and 6 and Chunshan 1, 2, 3 and 4, came from derivatives that Yong 368 (Common wheat) hybridized with Chunpin-11 (White chaff) (Triticale) and Synthetic wheat or Ae.Cylindrica, using pedigree method. These new germplasms did not have the same genetic background of Ningchun 4, a major wheat cultivar in Ningxia now. The quality of the new germplasm was obviously improved. Chromosome in situ hybridization test and HMW-G-S analysis showed that seven of ten newly created lines had 1B/1R translocation, and one line had translocation involving other R chromosomes.
