Molecular characterization of unsequenced plant species with complex genomes is now possible by genotyping-by-sequencing (GBS) using recent next generation sequencing technologies. This study represents the first use of GBS application to sample genome-wide variants of crested wheatgrass [Agropyron cristatum (L.) Gaertn.] and assess the genetic diversity present in 192 genotypes from 12 tetraploid lines. Bioinformatic analysis identified 45,507 single nucleotide polymorphism (SNP) markers in this outcrossing grass species. The model-based Bayesian analysis revealed four major clusters of the samples assayed. The diversity analysis revealed 15.8% of SNP variation residing among the 12 lines, and 12.1% SNP variation present among four genetic clusters identified by the Bayesian analysis. The principal coordinates analysis and dendrogram were able to distinguish four lines of Asian origin from Canadian cultivars and breeding lines. These results serve as a valuable resource for understanding genetic variability, and will aid in the genetic improvement of this outcrossing polyploid grass species for forage production. These findings illustrate the potential of GBS application in the characterization of non-model polyploid plants with complex genomes.

In crested wheatgrass, the species Agropyron cristatum includes populations that are diploid and tetraploid, either naturally or artificially induced. The species Agropyron desertorum is tetraploid and there are culitvars that are hybrids between A. cristatum and A. desertorum. The goal of this study was to compare the morphology (height, crown width, tiller density, tiller weight and tiller angle) of populations from the two species and hybrids, including S9240, a recently developed colchicine induced tetraploid A. cristatum. Data were collected in 1999 and 2000 from several different sward-seeded and spaced-planted trials. The four tetraploid crested wheatgrasses (A. cristatum “Kirk” and “S9240”, A. desertorum “Nordan”, and A. desertorum × A. cristatum “CD-II”) were significantly (P < 0.05) taller, narrower in row width, and produced fewer, heavier tillers than the diploid A. cristatum “Parkway”. Among the tetraploid populations, S9240 was significantly (P < 0.05) taller and produced fewer tillers. S9240 also produced significantly (P < 0.05) heavier tillers than CD-II and Nordan, and also than Kirk, one year of two. Row widths were variable among populations, but S9240 generally produced a narrower crown than other populations. Key words: Crested wheatgrass, polyploidy, plant height, crown diameter, tiller characteristics

Productivity and durability of 29- to 38-year-old stands of crested wheatgrass, Agropyron cristatum Gaertn., were assessed. Crested wheatgrass consistently outyielded the grass and sedge component of Mixed Prairie native range vegetation by a ratio that ranged from 12.42 to 1.08. Analysis of soils showed that exhaustion of N was not a factor in persistence of stands. The data indicated that, in the study area, seeded stands of crested wheatgrass became a permanent part of the vegetation and that yield was dependent mainly on current rainfall.
