TABLE 5.

Correlation analysis among ARO, GRAVY, the first two axes, GC3s, ENC and GC in the 56 PEDV strains.

		Axis1	Axis2	ENC	GC	A3s	U3s	G3s	C3s	GC3s
GRAVY	r	–0.198	–0.158	−0.353**	–0.203	–0.180	0.137	0.242	−0.331*	–0.015
	p	0.143	0.243	0.008	0.133	0.185	0.313	0.073	0.013	0.915
ARO	r	−0.445**	0.273	0.023	0.161	−0.373**	–0.123	0.339*	0.118	0.237

The numbers in each column represent correlation coefficient “r” values, which are calculated in each correlation analysis. “*” means 0.01 < P < 0.05; “**” means P < 0.01.
