1.  Yields calculated as 50 lb/bu at 8.5% moisture.
2.  2003 and 2001.
3.  Blackleg rated as total percentage of plants killed by blackleg or with severe basal stem canker.
4.  Lodging rating:  1.0 = all plants erect to 5.0 = over 80% of plants down.
5.  C.V. = 16.1%, and df for EMS = 69.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0.10).
Planted:	November 22, 2002.
Harvested:	May 29, 2003.
Seeding Rate:	5 lb/acre in 7" rows.
Soil Type:	Greenville sandy clay loam.
Soil Test:	P = Medium, K = High, and pH = 6.4.
Fertilization:	Preplant:  15 lb N, 60 lb P2O5, and 60 lb K2O/acre.
	Topdress:  60 lb N/acre on February 3, 2003 and 60 lb N/acre on March 11, 2003.
Management:	Subsoiled and rototilled.
Previous Crop:	Peanuts.
Test conducted by P. L. Raymer, A. E. Coy, M. D. Pippin, and R. R. Pines.
NOTE:  This variety test was located directly adjacent to a Phoma blackleg disease nursery and was inoculated              by spreading infected stubble over the field shortly after planting.
