Keys to Choosing a Resilient and Consistent Variety

• Consider varieties that have been tested in state, regional, or national variety trials for more than one year

• Select more than one variety per season

• A variety will only show maximum performance when managed appropriately

• Choose varieties that will return the greatest benefit to your farm

• If winter hardiness is a concern:– Plant the majority of your acres to a hardy variety

– Select a “variety of interest” for the remainder

– Look for varieties with winter survival scores of >60% or a 6 out of 10 rating in your area
