Table 2 Partitioning of variance within and among apricot groups and regions (average over 25 loci)

Source of variation	df	Sum of squares	Variance components	Percentage of variation
Among regions	2	311.75	1.353	7*
Among groups/regions	8	488.82	2.606	14*
Within groups	196	2840.47	14.492	79*
Total	206	3641.04	18.451

The group level considered the eleven apricot geographic groups and the region level encompassed the three main geographic regions: A (Iran and Turkey), B (Continental Europe, southern France and southern Italy), and C (Murcia, northern Tunisia, Moulouya Valley, Messaad, Oases of Tunisia and Draa Valley).
