Red flags attached to panicle bases.
(A) A square of red felt (4.5 cm × 4.5 cm) was cut from one corner to the center by scissors and (B) stapled around (C) a panicle base. (D, E) The spread of the red flags on the panicles depended on the HOMI-RIL (photographed from above). (F) The red flags were attached to every third plant in the middle row. This orthomosaic was made from photographs taken on 20 September 2018. The black lines delineate the HOMI-RILs.
