1.  Days from planting to 50% bloom.
2.  Disease rating (primarily Anthracnose) just prior to harvest:  1 = no disease to 10 = plant dead from disease.
3.  CV = 17.7% and df for EMS = 75.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
Planted: July 2, 2002.
