  1. Note: a the ratings of panicle blast disease. 0: no incidence of infected grains; 1: infected symptoms only at spikelets; 3: infected symptoms expand to second branches of a panicle; 5: infected symptoms expand to first branches of a panicle; 7: infected symptoms expand to the main branch of a panicle; 9: the whole panicle is infected severely.
