Although 'Teta de Vaca Blanca' had some seed- less berries, while others had 1-2 seeds, he did not actually We studied 142 grapevine seed samples belonging to describe any seedless cultivar. KOLENATI (1846) described 5 Vitis species, 92 cultivars of Vitis vinifera, 12 feral/wild the seedless 'Apyrena persica' from the Caucasus. His clas- populations and 4 hybrid rootstock cultivars.

Seeds show a wide range of variation in ENGELMANN (1875) first used seed parameters for clas- body dimensions, and in other parameters. Two largely sifying American Vitis species. PLANCHON (1887) defined differentiated clusters were obtained. Coincidences with Euvitis as bearing pear-shaped seeds, versus Muscadinia = previous seed classifications are discussed. Wild extra- Lenticellosis with seeds oblong to ovoid, with oval-oblong European species have smaller seeds. The index breadth/ chalaza surrounded by radial ridges and furrows. This dif- length (STUMMER’s index) doesn’t allow to separate wild ference is accepted in the Floras and monographs in the US grapevines and cultivars. It defines, however, the “wild (GRAY and FERNALD 1989, MUNSON 1909, REHDER 1990).
