摘要：The pip, as the most common grapevine archaeological remain, is extensively used to document past viticulture dynamics. This paper uses state of the art morphological analyses to analyse the largest reference collection of modern pips to date, representative of the present-day diversity of the domesticated grapevine from Western Eurasia. We tested for a costructure between the form of the modern pips and the: destination use (table/wine), geographical origins, and populational labels obtained through two molecular approaches. Significant structuring is demonstrated for each of these cofactors and for the first time it is possible to infer properties of varieties without going through the parallel with modern varieties. These results provide a unique tool that can be applied to archaeological pips in order to reconstruct the spatio-temporal dynamics of grape diversity on a large scale and to better understand viticulture history. The models obtained were then used to infer the affiliations with archaeobotanical remains recovered in Mas de Vignoles XIV (Nîmes, France). The results show a twofold shift between the Late Iron Age and the Middle Ages, from table to wine grape varieties and from eastern to western origins which correlates with previous palaeogenomic results.
