Narrative
Developed from a cross of BS5, as a source of earliness, and BS20, which contributed root and stalk strength. Germplasm of BS21 includes about 54% Reid Yellow Dent, 18% Minnesota 13, 13% European Flint, and 15% from sources of unknown origin. Seven cycles of reciprocal recurrent half-sib selection with BS22 as tester were completed. Selection emphasized greater grain yield and improved root and stalk strength. Direct response was 4.4% cycle-1 for grain yield. Maturity classification is AES 500-600.
