Abstract
Pea, one of the founder crops from the Near East, has two wild species:
subsp.
, with a wide distribution centered in the Mediterranean, and
which is restricted to Syria, Lebanon, Israel, Palestine and Jordan. Using genome wide analysis of 11,343 polymorphic single nucleotide polymorphisms (SNPs) on a set of wild
(134) and
(20) and 74 domesticated accessions (64
landraces and 10
), we demonstrated that domesticated
and the Ethiopian pea (
) were derived from different
genepools. Therefore, pea has at least two domestication events. The analysis does not support a hybrid origin of
, which was likely introduced into Ethiopia and Yemen followed by eco-geographic adaptation. Both
and
share traits that are typical of domestication, such as non-dormant seeds. Non-dormant seeds were also found in several wild
accessions which could be the result of crop to wild introgression or natural variation that may have been present during pea domestication. A sub-group of
overlaps with
landraces. This may be a consequence of bidirectional gene-flow or may suggest that this group of
is the closest extant wild relative of
.
