* A random quality sample was taken on the picker during harvest and ginned in small gin in the
SWVT Lab on the UGA Griffin Campus to determine lint fraction. A lint sample was sent to the
USDA classing office in Macon, Georgia, for quality testing.
Bolding indicates entries not significantly different from highest yielding entry based on Fisher's
protected LSD (P = 0.10).
