Analysis of molecular variance (AMOVA) based on 45 ISSR markers for the five populations of Juniperus phoenicea

Source of variation	d.f.	Variance component	% variation explained	P
Among regions	2	0·364	0·071	0·001
Among populations/within regions	2	0·846	0·164	0·001
Within populations	93	3·943	0·765	0·001

Regions analysed are ‘Sardinia’ with three populations and ‘Valdieri’ and ‘Cyprus’ with one population each.

P-values were estimated by a permutation procedure based on 999 replicates.
