Other claims from this paper (11)
- Observation A systematic prospection of former viticultural areas in the Beni Mellal-Khenifra region of the Moroccan Atlas led to the identification of 67 relict grapevines.
- Observation Genotyping of the relict grapevines with 13 nuclear SSR markers and 240 SNPs revealed 20 distinct genetic profiles.
- Observation Seven of the 20 genetic profiles corresponded to known cultivated varieties.
- Observation The remaining profiles were not found in international reference databases.
- Observation Several unidentified genotypes were detected repeatedly across distant locations, suggesting former local relevance for grape production.
- Observation Parentage analyses uncovered previously unreported familial relationships among Moroccan varieties.
- Observation Parentage analyses identified potential ancient key founder genotypes contributing to regional grapevine diversity.
- Observation A subset of relict plants displayed significant genetic contributions from V. vinifera ssp. sylvestris, indicating historical hybridization between the two subspecies.
- Observation The traditional grapevine assortment of the Moroccan Atlas was shaped by three main sources of genetic diversity: autochthonous Maghrebi varieties, introduced Iberian varieties and local sativa-sylvestris hybrids.
- Observation Uncatalogued genotypes and multiple partial parentage relationships highlight a high level of genetic erosion in Moroccan viticulture.
- Recommendation The authors state an urgent need for conservation, further agronomic evaluation and potential valorisation of Moroccan grapevine germplasm.
