The staging system employed here divides plant development into vegetative (V) and reproductive (R)
stages.Subdivisions of the V stages are designated numerically as V1, V2, V3, etc. through
V(n), where (n) represents the last leaf stage before VT for the specific hybrid under consideration. The
first and last V stages are designated as VE (emergence) and VT (tasseling). The (n) will fluctuate with
hybrid and environmental differences. The six subdivisions of the reproductive stages are designated
numerically with their common names
