Evaluation location: Iowa, United States. Method: Daucus direct seeded into two 4-foot rows 8 inches apart in NCRPIS Farm Greenhouse-3 sandbox measuring 8 ft. x 4 ft. x 2 ft (l x w x h) and filled to 20-inch depth with sand. Sandbox was watered as needed and seedlings fertilized with a liquid fertilizer twice weekly. Seedlings were thinned to 2 to 3 -inch spacing. Roots were carefully dug from the sand for notes/images after two to four months (or sooner if plants began to bolt). Root characterization notes/images were recorded on plants between 50 and 130 days after planting (DAP); average was 92 DAP. Notes/images recorded on 10 roots per accession.
