¹ Tolerance scores were assigned on a scale of 1 to 10 with 1 being completely tolerant and 10 being completely susceptible. The five individual columns under this heading present tolerance scores collected at one week intervals beginning at 21 days after planting. All scores are displayed as an average from two locations (Monroe and Lowndes Counties).

² Overall tolerance score averaged across all rating intervals and locations (p = 0.221).

These data are intended to serve as an additional resource for variety selection specifically for soils with a history of problems associated with iron deficiency chlorosis.
