Abstract: In  this  paper the karyotypes of eleven  species  of  Triticeae  from Northeast China are reported. The karyotype formulae are as follows: Agropyron cristatum,  2n=4x=28=20m+8sm;  Elytrigia repens,  2n=6x=42=34m(2SAT) + 8sm;  Hordeum  brevisubulatum,  2n = 4x = 28 = 20m + 8sm( 4SAT );  Roegneria nakaii,  2n = 4x = 28 = 20m + 8sm( 4SAT );  R.  turczaninovii  var. macrathera, 2n = 4x = 28 = 20m(2SAT ) + 8sm(2SAT ); Elymus sibiricus, 2n = 4x = 28 = 20m + 8sm ( 4SAT);  E.  dahuricus,  2n=6x=42=32m+10sm( 6SAT);  E.  excelsus, 2n=6x=42=32m+10sm( 6SAT); Leymus chinensis,  2n=4x=28=20m(4SAT) + 8sm; Roegneria ciliaris, 2n = 4x = 28 = 22m( 2SAT ) + 6sm( 2SAT ); R. kamoji, 2n= 6x = 42= 30m+ 12sm(4SAT). The karyotypes of the first five species are re-ported for the first time.
