In scientific publications of the early 2000s, the Greenfield variety is mentioned as an open-pollinated maize. Within the framework of comparative trials for the needs of organic farming, it was recorded that this variety is inferior to commercial hybrids in terms of yield and lodging resistance.
The name Greenfield is not included in the current registers of breeding achievements of Pioneer or Corteva Agriscience as a commercial hybrid. Descriptions of this variety found online that specify particular morphological characteristics lack official confirmation and may refer to other products or marketing materials.
