What we observed
- Peking varieties averaged +4.0 percentage points above PI88788 varieties across the four plots, and were ahead in 4 of 4.
- Top Peking results: 2697E 115% (Danforth); 32EJ12 109% (Danforth); 32EJ12 108% (Cabery).
- The Peking group is smaller and earlier on average, and SCN wasn’t measured in these fields — this shows where varieties landed, not why.
SCN source from the AgTech 2027 product reference; Stine lists “R” (resistant), shown here as PI88788. 3115XF (PI88788 + Peking) is not grouped. Danforth plots use the non-treated side; seed-treatment entries are left off.
