One field location of the Big BIT experiment. Pictured is each tester set in addition to the reference set. Approximately 2,500 maize lines were crossed with one of each tester set (an inbred line that matures relatively early, mid, or late) to assess more than 7,600 hybrid combinations for different agronomic and harvest traits.
