Abstract
Abstract According to the invention, there is provided a hybrid corn plant, designated 3471, produced by crossing two Pioneer Hi-Bred International, Inc. proprietary inbred corn lines. This invention thus relates to the hybrid seed 3471, the hybrid plant produced from the seed, and variants, mutants, and modifications of Pioneer hybrid 3471. This hybrid corn plant is characterized by superior qualities of good ear size, excellent late-season plant health and seedling (young plant) vigor, and fast dry-down in the field. 3471 is relatively tall and flowers late for its relative maturity classification.
