Hycrest Crested Wheatgrass (Agropyron cristatum x Agropyron desertorum)

Hycrest Crested Wheatgrass offers improved forage and yield over its parent species. It was developed at ARS in Logan, Utah by crossing Fairway and Desert Crested Wheatgrass (A. cristatum x A. desertorum). It has excellent seedling vigor and is easier to establish than either of it’s parents. It is very drought tolerant, establishes well on dry sites, and thrives in sagebrush communities.

It is best adapted to 5-9,00′ in elevation and does well on shallow to deep, coarse to fine textures, moderately well to well drained soils. It is not adapted to excessively saline areas.

CD-II is a selection of Hycrest realesed by Logan, UT ARS.
