Fig. 2 Cluster dendrogram of 27 smooth bromegrass clutivars or populations evaluated at three locations (Nebraska, North Dakota, and Wisconsin) for nine variables (first-harvest and regrowth forage yield, panicle height, maturity, ground cover, brown leafspot reaction, IVDMD, NDF, and N concentration). R2 = sum of squares among clusters ÷ total sum of squares among entries. Letters inside parentheses indicate meadow (northern) climatypes (M) or intermediate climatypes (I); all others are steppe (southern) climatype
