Effects of phenological traits on the expected proportion of pollen received from transgenic plants (PPR) of weedy B. rapa in mixed populations including transgenic B. napus crop and crop-weed hybrids.

A. The mean PPR for the transgenic type treatments. B. The influence of weedy traits. “Slopes” are the coefficients for the effect of each trait on PPR. The “overall” slope indicates the effect across all transgenic types. The within-type slopes were obtained from the mixed linear model presented in Table 3, they indicate the relationships for crop, F1 and backcross migrants. Coefficients that do not include zero in their 95% confidence interval are shown in bold typeface.
