Inheritance of Evolved Glyphosate Resistance in a North Carolina Palmer Amaranth (Amaranthus palmeri) Biotype : Table 1

Table 1: Percent survival of parent Palmer amaranth biotypes (GR and GS) and F1 families (R × S and S × R) after treatment with glyphosate*.


Biotype	Herbicide rate (g/ha)
	180	400	2000	3000
		%

GR Parent	—	—	44a	32a
GS Parent	10b	3c	—	—
F1 R × S	86a	81a	22b	10b
F1 S × R	83a	68a	22b	4b

* Abbreviations used: GR: glyphosate-resistant; GS: glyphosate-susceptible; R × S and S × R: reciprocal crosses where, the first alphabet denotes female parent. Means within a glyphosate rate followed by the same letter are not significantly different according to Fisher’s Protected LSD test at .
