Values are variance components±SE. Analysis was performed both within each treatment (LDV: long days, vernalized plants; LD: long days, nonvernalized plants; SDV: short days, vernalized plants) separately, and also on the combined data set. ANT: anthesis; AvgPHY: phyllochron relative to all the leaves BOOT: booting; FLA: flag leaf; LN: leaf number; PEN: penultimate leaf; PHY28: phyllochron relative to the leaves 2–8; TRA: transplanting; TS: terminal spikelet.
