Hybrids between the Chinese endemic species Psathyrostachys huashanica KENG and the SW. Asian species P. fragilis (BOISS.) NEVSKI (all 2n = 14) developed normally but were completely sterile. Meiotic analyses revealed a high chiasma frequency indicating that the two species as well as P. juncea (FISCH.) NEVSKI share the same basic genome (called N). The hybrid nature of the plants was established through karyotype analysis and Giesma C-banding.
