Mediterranean Hedysarea species constitute important phytogenetic resources able to promote forage production and to valorize grasslands currently damaged by severe genetic erosion. The study of genetic diversity in nine Mediterranean Hedysarea species found in North Africa was performed using the AFLP technique. The eight primer combinations generated, on(More)
Powdery mildew, caused by Sphaerotheca pannosa var. Persicae, is one of the most important diseases in apricot production areas around the world. The transmission of resistance to powdery mildew and the identification of related quantitative trait loci (QTLs) were analysed during 3 years in two F1 apricot progenies derived from the crosses ‘Bergeron’ ×(More)
Domestication generally implies a loss of diversity in crop species relative to their wild ancestors because of genetic drift through bottleneck effects. Compared to native Mediterranean fruit species like olive and grape, the loss of genetic diversity is expected to be more substantial for fruit species introduced into Mediterranean areas such as apricot(More)
Apricot was introduced into the Mediterranean Basin from China and Asian mountains through the Middle-East and the Central Europe. Traditionally present in Tunisia, we were interested in accessing the origin of apricot species in the country, and in particular in the number and the location of its introductions. A set of 82 representative apricot accessions(More)
In order to optimize the management of genetic resources, in most cases a representative sample of the germplasm collections needs to be developed. The establishment of a core collection is thus of major importance either to minimize the cost associated with the management of the associated germplasm or to apply analysis onto representative bases. In order(More)
Phylogenetic relationships in the Lathyrus genus were examined using cpDNA data, particularly data attributed to the "barcode" rbcL gene to construct a possible evolutionary scenario. Plant barcoding can be used to differentiate between species within a genus and to conserve DNA within the same species. We assessed the phylogeny of 29 species of Lathyrus(More)
Sequence-related amplified polymorphism (SRAP) markers were used to evaluate the intra- and interspecific variation among 40 Lathyrus genotypes (four species) (Fabaceae). Ten SRAP primer combinations resulted in a total of 94 bands, and they exhibited high interspecific variability. The genetic differentiation among Lathyrus, estimated using AMOVA, was(More)
Amplified fragment length polymorphism (AFLP) has been proposed as a valuable tool for finding molecular markers linked to QTL controlling architectural trait. Segregation of polymorphic AFLP fragments was followed in F2 offsprings Hedysarum coronarium derived from two native wild accesions crossing: Jebel Zit x El Haouaria, which had previously(More)
Tunisia is rich in diverse forage and pasture species including perennial ryegrass. In order to enhance forage production and improve agronomic performance of this local germplasm, a molecular analysis was undertaken. Random amplified polymorphic DNA (RAPD), inter simple sequence repeats (ISSR) and morpho-agronomical traits markers were used for genetic(More)
Medicago ciliaris L., considered as a valuable genetic resource, is a good candidate for the improvement of marginal or degraded lands with low fertility or high salinity. In this study, the pheno-morphological and genetic diversity were investigated in 14 Tunisian populations of M. ciliaris for the first time. Fourteen morphological traits showed(More)
