Analyses of molecular variance (AMOVA) for Alternaria isolates by SRAP markers.

Source	Df	SS	MS	Est. var.	%	PhiPT
Among populations	6	128,147	21,358	0.175	1%	0.009	0.414
Within populations	38	774,431	20,380	20,380	99%
Total	44	902,578		20,555	100%

Df: degree of freedom; SS: sums of squares; MS: mean squares; Est. var: estimate of variance; %: percentage of total variation; PhiPT: phi-statistics probability level after 999 permutations; is based on 999 permutations.
