Inheritance of Evolved Glyphosate Resistance in a North Carolina Palmer Amaranth (Amaranthus palmeri) Biotype

Figure 1

Glyphosate dose responses of glyphosate-resistant (GR), glyphosate-susceptible (GS), F1 R×S (GR female × GS male), and F1 S×R (GS female × GR male) Palmer amaranth populations. Points are mean values ± S.E. Best fit curves for these respective populations are: 𝑦=13.4−2.7𝑥, 𝑃=0.0390, 𝑟²=0.92; 𝑦=12.4−4.2𝑥, 𝑃=0.0221, 𝑟²=0.96; 𝑦=14−3.1𝑥, 𝑃=0.0246, 𝑟²=0.95; and 𝑦=15−3.7𝑥, 𝑃=0.0170, 𝑟²=0.97.
