aSusceptible Yield Index is: 100%  100%
Susceptible Yield (RR): 2.55 T/ha or 37.9 bu/ac 2.36 T/ha or 35.0 bu/ac
Susceptible Yield (Conv): 2.44 T/ha or 36.2 bu/ac 2.08 T/ha or 30.8 bu/ac
* Roundup Ready (RR) varieties, tested under a RR management system.
a Susceptible Yield Index is based on three high yielding susceptible varieties.
Test locations had low to moderate SCN infestations (2,000 to >4,000 eggs/100g of soil).
Resistance source is PI88788 for all varieties listed.
