Big yielder with stalks and roots to match! Excellent early vigor. Strong defensive package leads to consistently strong performance across most soil types. High level tolerance to anthracnose stalk rot. Handled dry soils well.


Only average on gray leaf spot tolerance.


Very good all-around hybrid with excellent yield potential! Ear has some flex for both length and girth. Plant this one first. Will reward you for slightly higher plant population and good fertility.
