Breeding for Resistance to PLHHigher Resistance,
Improved Agronomics
Progress in breeding alfalfa for improved
resistance to potato leafhopper

• Increased PLH resistance
• 30 86 resistance
• Later fall dormancy
• FD2 FD4
• Better DRIs (30/30)
• Improved forage yield
• gt 100 of checks
• Longer stand life

WL 353LH

• New 7th generation leafhopper resistance (first
  to market!)
• Dramatic improvements in agronomic performance
• PLH resistance nears 87
• Impressive visual appeal under severe PLH
  pressure
• No-Spray Anytime, Anywhere!
