Henan East Henan crop Variety Exhibition Center and Institute of Genetics of Chinese Academy of Sciences adopted Heixigo international triticale variety MZALEONDBA-TR as female parent and Yumai 2 as male parent after distant crossing (pedigree number (84) 184). The 1BL/1RS translocation line was bred by using F6 generation 84 (184) 1 hexaploid triticale intermediate material as female parent and 90 selection line as male parent.
