“…Because these species have excellent traits such as disease resistance, insect resistance, drought tolerance, and salt tolerance, which are lacking in wheat crops, they are important germplasm resources in wheat breeding (Li et al, 2021). This group of forage grasses is widely distributed, mainly in Central Asia, Russia, Mongolia, China, Korea, Japan, and northern India.…”

The relationship between the genetic diversity and genetic characteristics of wild plant germplasm can provide insights for better utilization and conservation of genetic resources. Bunchgrass species in the genus Elymus are important for forage and grassland restoration in Northwest China. In this study, eight phenotypic traits were evaluated in 81 accessions of four Elymus species in the northwest region of China, and genetic diversity analysis was performed using 16 simple sequence repeat (SSR) markers. In the phenotypic trait analysis, Elymus sibiricus had the highest coe cient of variation for single-plant weight(58.24%) and the lowest coe cient of variation for the number of spikelets(0.005%). Clustering based on phenotypic traits placed all varieties into four groups, which were also supported by principal component analysis (PCA). 16 pairs of SSR markers were screened with high polymorphism, with a polymorphism information content (PIC) range of 0.3648-0.7794 and an interspeci c PIC range of 0.465-0.611 in Elymus species. The unweighted pair-group method with arithmetic mean approach applied to SSR marker data also divided the 81 accessions into four groups, similar to the results based on phenotypic traits. The results of PCA and population structure analysis based on SSR data were similar. The ndings presented here will facilitate the collection and conservation of Elymus germplasm resources and provide theoretical references for the future classi cation, breeding, innovation, utilization, and conservation of germplasm.

The development of seed vigour testing methods is important for high seed quality selection and, consequently, ensuring high seedling emergence and uniform establishment in the field, particularly in harsh environments. In this study, standard germination (SG), germination under water and temperature stress conditions, radicle emergence (RE) count, accelerated ageing (AA), and electrical conductivity (EC) tests were applied to evaluate the vigour of Poa crymophila and Elymus dahuricus seed lots. SG ranged from 70 to 88% for P. crymophila and 81 to 97% for E. dahuricus, with no significant correlation with field emergence (FE) for either species. EC was significantly correlated (r = -0.774, P < 0.05) with FE for P. crymophila seeds, but not for E. dahuricus. RE counts at 144 and 108 hours from sowing for P. crymophila and E. dahuricus, respectively, were significantly correlated with FE. Germination after one day of AA for P. crymophila and four days for E. dahuricus were more closely correlated with FE than other AA periods. Germination at -0.2 MPa and 15°C for P. crymophila, 0.0 MPa and 20°C for E. dahuricus also related to field emergence.
