Analyses of molecular variance (AMOVA) based on cpDNA and nuclear DNA from C. flavida.

		Chloroplast DNA	Nuclear DNA
Grouping	Source of variation	Percentage of variation (%)	Percentage of variation (%)
Varieties	Among varieties	63.46**	17.81**
	Among populations within varieties	34.78**	28.92**
	Within populations	1.76**	53.28**
SAMOVA groups	Among groups	57.95**	31.19**
	Among populations within groups	39.87**	17.23**
	Within populations	2.18**	51.58**
var. flavida 1	Among populations	100.00**	22.77**
	Within populations	0.00**	77.23**
var. flavida 2	Among populations	100.00**	32.90**
	Within populations	0.00**	67.10**
var. patens	Among populations	79.25**	31.68**
	Within populations	20.75**	68.32**

A priori groupings were: (1) two varieties of C. flavida and (2) three SAMOVA groups of PAL marker, including var. flavida 1 (ND, MQ, NF, DY, LLS, LR, SC, NX, LM, LL, MZ, and LD); var. flavida 2 (BZ, LX, and LN); and var. patens (SG, LHS, NXS, NGL, and WM).
