Description
Seedling coleoptile color was scored in the Synthetic x Opata RI population.
Protocol
Coleoptile color was rated on a scale of 0 (green) to 5 (relatively darkest red-purple coloring) in 5-day-old seedlings grown in Petri dishes under fluorescent light in a growth chamber at around 20oC.
Environment
Growth chamber Synthetic/Opata, Ithaca
