Narrative
Hybrid wheatgrass. The original seedlot, MH-114-1085, described in the collection notes as Agropyron sp., was included the NPGS as Elytrigia repens (PI 593438). This germplasm is the result of five cycles of recurrent selection for caespitose growth habit, vegetative vigor, leafiness, seed set, plant color, and freedom from plant pests. Based on chromosome pairing in intra- and interspecific hybrids, germplasm originated from a natural hybrid between quackgrass and an Asian relative of North American bluebunch wheatgrass and has a chromosome number of 2n=6x=42 with a genomic constitution of StStStStHH. This germplasm is less rhizomatous (58 vs. 83 cm), tall in stature (1007 vs. 934 mm), and has longer flag leaves (213 vs. 164 mm) than NewHy. Salinity tolerance comparable to NewHy, but less than tall wheatgrass (Thinopyrum ponticum).
