This study clarifies many aspects of size and shape (co)variation between pip and berry in both wild and domesticated Vitis vinifera.The covariation of berry size, number of seeds per berry (‘piposity’), pip size and pip shape were explored on 49 grapevine accessions sampled among Euro-Mediterranean traditional cultivars and wild grapevines. Consequences for archaeobotanical studies are discussed through the prediction of berry dimensions from archaeological pips from a Southern France Roman site.For wild grapevine, the higher the piposity, the bigger the berry and the longer the pip. For wild and domesticated grapevine, the longer is the pip, the more it has a « domesticated » shape. Such covariations allow to infer the berry dimensions in archaeological context where only the pips are recovered.This systematic exploration sheds light on new aspects of pip-berry covariation in both size and shape, draws the curtain on grapevine eco-evo-devo changes during domestication, and invites to explore the impact of cultivation practices on pip shape.
