Third Generation Hybrid Alfalfa


Using patented hybrid technology, HybriForce-3400 brings the same performance level producers have come to expect from hybrids in other crops such as corn and canola. HybriForce-3400 is the third generation of HybriForce alfalfa hybrids that deliver unsurpassed forage yield potential. HybriForce-3400 has shown a 5% yield advantage over competitors in extensive research trials (data set of 746 cuts).

HybriForce-3400 delivers exceptional seedling vigor and hybrid performance rewarding growers for many harvests after establishment. Its exceptional regrowth, plant vigor and fine stems allow for more aggressive cutting regimes to yield more and better quality forage. Hybrids by design deliver more yield in the field over commercially produced synthetic varieties.

Yield Protection for Alfalfa Begins with Seed Production 

MsSunstra hybrid alfalfa technology protects the forage yield potential in the commercial seed you purchase. How is this accomplished? It is accomplished by controlling pollination with the patented MsSunstra seed production process. Other alfalfas cannot control pollination to this degree. Non-hybrid alfalfa commercial seed suffers yield loss from inbreeding as a result.
