K.stenachyra was hybridized with Elymus caninus,Roegeneria kamoji and K.hirsuta. The chromosome pairing behavior at metaphase I in the parents and hybirds was observed. Meiotic configurations are 23.79I+5.20II+0.27III for E.caninus×K.stenachyra,18.23I+11.68II+0.06III+0.06IV for R.kamoji×K.stenachyra,and 4.83I+17.31II+0.55III+0.20lV+0.02V for K.hirsuta×K.stenachyra. Based on the chromosome pairing in the hybrids,and species morphology,K.stenachyra should be correctly grouped in Kengyilia rather than in Roegneria.
