PAC 456 is a tall, high yielding dual purpose hybrid with a large bulky canopy and long harvest window. Purpose bred in Europe for dry matter and energy production.
PAC 456 can have a high ear placement particularly if planted at high rates, this means that planting rates should not go above 90,000 seeds/ha for grain crops. However, good grain quality, yields, drydown, standability and plant integrity during grain drydown make this hybrid a top performer for both grain and silage. Husk cover is very good and ears are large and packed with large deep kernels ensuring silage of high grain content and energy.
