1Percent first harvest from Stoneville, Tunica, and Elizabeth in 1995, from Stoneville and Sumner in 1994, and from Stoneville and Tunica in 1993. Higher values indicate earlier maturity. NAWB5 = Days from planting until uppermost first position white bloom is 5 nodes from the terminal; data from Stoneville in 1994 and 1995, and Tunica in 1995. Lower values indicate earlier maturity. NACB = Nodes from uppermost first position cracked boll to terminal; data collected 10 to 21 days before defoliation; data from Stoneville in 1994 and 1995, and Tunica in 1995. Lower values indicate earlier maturity. Values in bold type indicate varieties that are not statistically later than the earliest maturing variety according to each measure of maturity.
