Notes:
1Tolerance scores were assigned on a scale of 1 to 10 with 1 being completely tolerant and 10 being completely susceptible. The six individual columns under this heading present tolerance scores collected at different rating intervals throughout the growing season. All scores are displayed as an average from two locations (Monroe and Lowndes Counties), except for the sixth column, which is from Monroe County only.
2Overall tolerance score averaged across all rating intervals and locations (p < 0.0001).
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. For detailed information on variety performance, consult other sources such as the results from official variety trials and demonstration programs.
