Recorded as DAP, when four tillers from a plant had exerted panicles. Up to five plants per plot were marked for characterization, based on the apparent morphological variation. ^bMeasured from the base of the panicle to the tip of the flag leaf of the main culm. ^cFive panicles were measured per plant. ^dDetermined by applying equal force to each sample, as described in “Materials and Methods.”
