Going Forward
• Last winter wheat crosses were conducted in Harrington in 2008. New CAP proposal will equate to renewed breeding efforts.
• Aim is to continue a program targeting local adaptation• delivery of new winter wheat cultivars with high grain
yield, superior disease resistance and improved winter survival
