aSusceptible Yield Index is: 100% 100%
Susceptible Yield (RR): 3.11 T/ha or 46.2 bu/ac 3.14 T/ha or 46.5 bu/ac
Susceptible Yield (Conv): 3.40 T/ha or 50.4 bu/ac 3.33 T/ha or 49.4 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 Peking for 92M52, and PI88788 for remaining varieties.
