  1. Percent germination and transgenic frequencies were calculated for the parental (BN: B. napus; BR: B. rapa; TM(H) and hybrid BC1/F2 populations (GT1, GT5, GT9, and TM) pre-season and post-harvest. Transgene persistence data reported here only applies to gene flow from GT hybrid plots and not TM hybrid or homozygous plots. Column MS represents transgenic ratio mean separation obtained by Fisher's LSD (P < 0.0001). Data was rank transformed and SAS software was used for data analysis.
