摘要： Total of 39 germplasm materials including five species of Agropyron Gaertn. and seven species of Roegneria C. Koch, were studied in this thesis. Six methods such as morphology, physiology, gliadins, isozyme, ISSR molecular markers and production performance were used on the population samples. The aim of our study was to identify, analyze and make comprehensively research on the above germplasm materials. The main results obtained were as follows;The materials of two genera were tested in morphology methods existed abundant genetic variation. There were six physiological factors that affected Agropyron Gaertn. and Roegneria C. Koch, leaf physiological and metabolic functions. Gliadin was polymorphic. The bands of peroxidase and esterase had the significant difference. Gene diversity was rich. Production performance was significant difference. Clustering results showed that relationships of species confirmed the scientific traditional taxonomy of two genera once again. The genetic relationship and evolution among species analysis suggested that A. derstorum maybe a derivative species of A. cristatum and A. monogolicum, and A. cristatum. vox. pectinforme was a variant of A. cristatum;It was concluded that R. nutans and R. dura which was belong to Htde glume group were in the original state, but R. turezaninovii var. turczaninovii which was belong to long glume group were in the evolution state.
