* NAWB5 = Days from planting until uppermost first position white bloom is 5
nodes from the terminal; data from Stoneville only. NACB = Nodes from upper
most first position cracked boll to the uppermost boll that is likely to be
harvested. % Open = Percent of total bolls open. NACB and % Open are means
from Stoneville (evaluated 128 days after planting) and Sumner (evaluated
151 days after planting).
** Stoneville LA887 included in this test as a mid-season check variety.
