Narrative
Hycrest II crested wheatgrass (Agropyron cristatum L.) is intended for use on arid and semiarid rangelands as a rapid establishing revegetation grass in the Intermountain Region and Northern Great Plains of western U.S. Hycrest II was selected for improved seedling establishment under drought. Hycrest II has a narrower genetic based than cultivars Hycrest and CD-II and has been evaluated on rangeland sites in western U.S. for seedling establishment compared to commercially available cultivars Hycrest and CD-II. When planted at a rate of one pure live seed (PLS), Hycrest II had more seedlings per unit area (m2) during the establishment year than did the cultivar Hycrest at Blucreek, UT (76 vs 65%); Green Canyon, UT (78 vs 61%; P<0.05); Mandan, ND (78 vs 69%; P<0.05)); Miles City, MT (85 vs 72%; P<0.05); Dugway, UT (35 vs 10%; P<0.05); and Curlew Valley, ID (72 vs 56%; P<0.05) (Fig. 1). At Dugway, UT, Hycrest II (35%) had significantly more seedlings per unit area than did CD II (13%) (Fig. 1). At Miles City, MT Hycrest II had significantly better seedling establishment than Nordan (Fig. 1). Due to Hycrest II increased seedling establishment potential, particularly under harsh dry environments, it is intended to replace the cultivar Hycrest for use on reseeding severely disturbed range sites on heavier soils receiving less than 300 mm of annual precipitation.

Pedigree
Description:
The original parental germplasm of Hycrest II was generated by intercrossing ten induced tetraploids of Fairway crested wheatgrass (PI 279802). From 1976 to 1985, this induced tetraploid population under went four cycles of recurrent phenotypic selection for seedling vigor, seed yield, and visual plant vigor at Stone, ID, Blue Creek, Logan, and Nephi, UT. In 2003, 660 plants per entry (3,960 total plants) were spaced-planted in a completely randomized design near Logan, Utah and designated as breeder seed.
