Narrative
Goldmine was evaluated as Kaw C3 in two sets of forage evaluation trials at Mead, Clay Center, and Concord, NE during the period 1999 to 2002. 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 Goldmine had moderately greater IVDMD than Kaw when harvested before heading or as regrowth. Forage yields of Goldmine were significantly greater than those of Kaw when hay was harvested after heading. Goldmine had greater forage yields and forage IVDMD averaged over all trials and harvests than the cultivars Pawnee, Rountree, and Niagara. Goldmine was compared to Kaw in a replicated grazing trial located near Mead, NE during the period 2000 to 2003. Based on weekly samples during the grazing season, forage availability and IVDMD were similar between Goldmine and Kaw but forage of Goldmine had greater crude protein concentration. In the three years of the trial, cattle grazing the Goldmine pastures had 7% greater average daily gain than cattle grazing Kaw pastures. Goldmine pastures produced 5% more beef cattle gains per acre than Kaw pastures. Based on an economic analysis, the increased gain by cattle grazing Goldmine pastures in comparison to Kaw pastures resulted in an increase of $11 per ha net return. Goldmine can be distinguished from Kaw by its moderately greater forage IVDMD, its greater flag leaf length and width, and a greater percentage of plants with reddish brown glumes and peduncles. It is similar in to Kaw and later in maturity than Pawnee, Bonanza, and Rountree. Goldmine is recommended for use in USDA Plant Hardiness Zone 6 and lower Zone 5.

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