| Abstract: | The karyotypes of 8 species in Kengyilia are analyzed in this paper.4 species of them are reported for the first time.The karyotype formulae are as follows: K.alatavica ,2n=6x=42=36m 6sm; K.longiglumis ,2n=6x=42=36m 6sm; K.grandiglumis ,2n=6x=42=36m 6sm; K.stenachyra ,2n=6x=42=36m 6sm; K.kasgarica ,2n=6x=42=32m 10sm; K.thoroldiana ,2n=6x=42=36m 6sm; K.melanthera ,2n=6x=42=36m 6sm; K.nana ,2n=6x=42=34m 8sm.All the karyotypes belong to 1B or 2B.No satellites have been found. |
