Table 3.
Independent t‐tests for fitness‐related traits between transgene‐present (+) and transgene‐absent (−) hybrid lineages in pure planting. Values in brackets indicate standard errors (SE). Values in bold followed by asterisks indicate significant differences between the corresponding transgene‐present and transgene‐absent lineages
