Table 2.
Three‐way anova for the fitness‐related traits of transgene‐present and transgene‐absent F2 hybrid lineages in pure and mixed planting. Three factors (transgene, genotype of weedy rice accessions, and planting mode) were included in the analysis. Transgene (T) had two levels (with or without transgenes). Genotype (G) had five levels (five weedy rice populations). Planting mode (C) had two levels (pure versus mixed planting)
