* Deltapine 50 included in this test as an early maturing check variety.
** NAWB5 = Days from planting until uppermost first position white bloom is 5
nodes from the terminal; data from Stoneville only.
NACB = Nodes from the uppermost 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 144 days after planting)
and Sumner (evaluated 151 days after planting).
