The species can be identified by its dark green, glossy and hairless leaves that are rolled in the bud. Auricles are well-developed and the ligules are long and membranous.

Figures 1 and 2 below represent the cumulative rainfall since 10/1/2017 and the cumulative growing degree days (GDD) for wheat since 11/21/17, when we planted our experimental trials in Davis (each is compared to a 10-year...
