Narrative
Bonanza was evaluated as Pawnee C3 in two sets of multi-year forage evaluation trials at Mead, Clay Center, and Concord, NE during the period 1999 to 2002 to evaluate the hay production potential. Concord and Mead are in the tallgrass prairie ecosystem in Plant Hardiness Zones 4 and 5, respectively, while Clay Center is in the transition zone between the tallgrass and midgrass prairie ecoregions in Plant Hardiness Zone 5. One set of trials was managed for hay harvest at the mid to late boot stage of physiological development while the other set was managed for hay harvest after inflorescences were emerged which was about a month later. Forage of Bonanza had significantly greater IVDMD than Pawnee averaged over all trials and had equivalent forage yields. It had greater digestibility than the big bluestem cultivars Rountree and Niagara that can be grown in the same regions. Bonanza was compared to Pawnee in a replicated grazing trial located near Mead, NE during the period 2000 to 2003. Based on weekly samples during the grazing season, there was more forage available in the Bonanza pastures and the forage was significantly higher in IVDMD than in the Pawnee pastures. In the three years of the trial, cattle grazing the Bonanza pastures had 16% greater average daily gain than cattle grazing Pawnee pastures. Bonanza pastures produced 14% more beef cattle gains per acre than Pawnee pastures. Based on an economic analysis, the increased gain by cattle grazing Bonanza pasture in comparison to Pawnee pastures resulted in an increase of $37 per ha net return. Bonanza can be distinguished from Pawnee by its greater forage IVDMD, its greater flag leaf length and width, and a smaller percentage of plants with brown or dark brown glumes and peduncles. It is earlier in maturity than Kaw or Goldmine, similar in maturity to Pawnee, and later in maturity than Rountree, Niagara, and Bison. It is recommended for use in USDA Plant Hardiness Zone 5 and lower Zone 4.

Pedigree
Description:
Developed by 3 generations of breeding using a modified restricted, recurrent selection breeding sytem in which forage yield and forage in vitro dry matter digestibility were the main selection criteria. The base population was the cultivar Pawnee. Each generation, selected plants were intermated in isolation to produce seed to start the next generation of selection.
