Near grain maturity, observe the proportion of panicles that have whiteheads. Use an augmented experimental design with a susceptible check replicated at intervals across the whole trial. Dissect stems from 10 hills of susceptible checks at maximum tillering, panicle initiation and late ripening, in order to identify the SB species. The test is considered a valid test for resistance if the susceptible check has more than 10% of panicles with whiteheads
