Grapevine Cultivar Mantonico bianco is the Second Parent of the Sicilian Catarratto

摘要

Molecular data provided evidence of the very ancient presence of Mantonico bianco in southern Italy and its genetic relationship to several southern Italian grapevine varieties. Using 47 SSR markers, we showed that Mantonico bianco is the complementary genitor, with Garganega (syn. Grecanico dorato), of Catarratto, currently the main autochthonous white wine grapevine of Sicily and one of the most widely cultivated varieties in Italy. We discovered a first-degree relationship between Mantonico bianco and Guardavalle, a widespread, primary autochthonous white wine grape of the Calabria region. SSR data also shed light on the identity of the Mantonico/Montonico cultivars and revealed the wide spread of one, Montonico bianco, in central and southern Italy.
