An international team of researchers, led by the Institute of Vine and Wine Sciences (ICVV) in Logroño, has discovered 'missing links' in the process of viticulture domestication in Montenegro. The study, published in the journal 'Scientific Reports', reveals the survival of primitive grape proto-varieties in Montenegro, providing insight into the ongoing domestication process of the grape. The research involves a genetic analysis of grapevines in Montenegro, identifying intermediate forms between wild and domesticated subspecies, suggesting a continuous flow of genetic material between the two. The findings offer a unique perspective on the early stages of vine domestication and the development of current vine varieties.
