Percentage of individual kernels expressing Bt proteins in SmartStax maize in pure Bt, pure non-Bt, and RIB plantings*.

*Means in the table were overall means across three trials (Table S1). In each field trial, 5 individual kernels per ear with 10 ears were examined for ears of pure Bt maize plantings (Pure Bt); 25 kernels per ear with 10 ears were tested for ears of pure non-Bt maize plantings (pure non-Bt); and for refuge ears in RIB (RIB refuge), 5 individual kernels per ear with 13 ears were assayed.sObserved frequencies do not fit the assumption of independent segregation in χ2-tests (PTable S1).Percentage of individual kernels expressing Bt proteins in SmartStax maize in pure Bt, pure non-Bt, and RIB plantings*.
