Table 4.
Paired t‐test for fitness‐related traits between transgene‐present (+) and transgene‐absent (−) hybrid lineages in mixed planting. Values in brackets indicate standard errors (SE). Values in bold followed by asterisks indicate significant differences between the paired transgene‐present and transgene‐absent lineages
