%X 'patr¨ªcia' grape of black, fleshy, round, 20¡ã brix and low acidity berries, has risen through hybridization between 'soraya' (iac 501-6) and selection iac 544-14, made in october 1959 at the instituto agron£¿mico, campinas (iac). commercial vineyards of this cultivar were set since 1970 in jundia¨ª, itupeva and atibaia regions of s£¿o paulo state, expanding to north paran¨¢ and s£¿o francisco valley in northeastern brazil. in 1980, in a commercial vineyard at ch¨¢cara extra vitis, bairro do poste, jundiai, s£¿o paulo state, brazil, two bunches of white berries were observed in one plant twig of cultivar patr¨ªcia. such twig was marked and in the winter of the same year it was used for grafts. all grafts gave also bunches with white berries. in 1981 winter new grafts were made with twigs of these plants at ch¨¢cara extra vitis and at esta£¿£¿o experimental de jundia¨ª (iac) which confirmed the presence of white berries bunches. such observation shows a somatic mutation of 'patr¨ªcia' (iac 871-41) which was named patr¨ªcia branca.
