TABLE 1.

Evaluation of dw3 reversion frequencies in msh1-derived genotypes and isogenic wild-type Tx430.

	Genotype	Total plant tested	Number of revertants	Reversion frequencies	P-value
Greenhouse	Epi-F1 (MSH1 memory line × Tx430)	602	3	0.50%	0.625
	Tx430 × Tx430 F1 control	547	3	0.55%	0.354
	MSH1 memory line	472	0	0	1.000
Field	Tx430 WT	6,650	10	0.15%	1.000
	Epi-F2 (MSH1 memory line × Tx430)	3,876	5	0.13%	1.000
	Tx430 × Tx430 F2 control	4,502	3	0.07%	0.383

Fisher’s exact test with α = 0.05 is performed to test significance.
