ns = not significant.
†SC = stand count, EV = early vigor (28 June to 29 June), LV = late vigor (20 Aug. to 21 Aug.), IDC = iron deficiency chlorosis score, CC = canopy closure (at R6), PH = plant height, TKW = thousand kernel weight, GY = grain yield, PC = protein content, OC = oil content, LP = lowest pod height, 1S to 4S = number of pods per plant with one to four seeds, TS = total seeds per plant, TP = total pods per plant, SP = average seeds per pod.
‡IDC is averaged over five environments due to no visual IDC differences at Prosper.
§Based on a visual score, with 9 being the most vigorous.
¶Based on the visual scale from Goos and Johnson (2008), with 5 being most chlorotic.
