Abstract
Modern agriculture results in the erosion of genetic diversity.
Hence, the collection and characterization of local germplasm becomes necessary.
We characterized 82 accessions collected during three expeditions and those from Senegalese Institute of Agricultural Research (ISRA)/ Horticultural Development Center (CDH) gene bank.
They were 48 accessions of Hibiscus sabdariffa, 19 accessions of Vigna unguiculata, 9 accessions of Amaranthus spp., and 6 accessions of Moringa oleifera. Descriptors of IPGRI, AVRDC-GRSU and Bricage were used.
This characterization shows the existence of an intra-specific diversity of the four species studied.
Seeds can also spread up to 800km depending on the variables used.
On average, it is noted that 35% of the accessions were found twice.
The agro-morphological characterization should be complemented by other studies using biochemical and molecular tools in order to verify the above results.
In order to increase the adoption rate of the new cultivars of the traditional leafy-vegetables, a participatory selection based on users preferences, was carried out at CDH research station, with involvement of the users (producers, consumers and traders). These new cultivars are now disseminated using on farm conservation in three pilot sites in the country and at research station.
