Resumen :
The pea (Pisum sativum L.) is arguably an
important winter pulse crop and a fundamental source
of proteins for human and animal nutrition. In Tunisia,
pea cultivation is characterized by its instability,
especially in the arid region of Southern Tunisia. We
carried out an investigation of the agro-morphological
and genetic diversity of 12 local pea accessions
cultivated in the arid region. We analyzed 21 quali-
tative and 26 quantitative traits following the UPOV
descriptors. Furthermore, 8 SSRs were employed to
examine genetic polymorphism, differentiation, and
population structure. Molecular and agro-morpholog-
ical data distinguished all the accessions under inves-
tigation. A considerable phenotypic diversity among
accessions was observed for many characters, includ-
ing some related to agronomical performance. At the
molecular level, all the SSRs were polymorphic, with
an average of 0.44 PIC value per locus. Our work
indicated the presence of a wide-ranging variation
among the local pea accessions evaluated. The overall
results indicated that the agro-morphological traits and
SSR markers were reliable and effective for assessing
the genetic diversity of phenotypic pea accessions.
