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.
