摘要：
Intergeneric hybridization between Elymus anthosachnoides (2n = 28, SSYY) and Psathyrostachys huashanica (2n = 14, NN) was performed. Three hybrid plants, obtained via embryo rescue, were intermediate between the parents in morphology and developed vigorously, but were completely sterile. The mean chromosome configuration was 19.48 I + 0.76 II per cell in the hybrids at meiotic metaphase I. This result indicates that E. anthosachnoides and P. huashanica are distantly related and that there is little or no homoeology between N (P. huashanica) and S or Y (E. anthosachnoides) genomes.
