Vespolina name are still unclear. Through its parent-offspring relationship with Nebbiolo, Vespolina is a half-sibling of several Piemontese wine grape varieties including: Bubbierasco, Brugnola, Freisa, Nebbiolo rosé, Negretta, Neretto di Bairo and Rossola nera. The grape Vespolina is known under a variety of synonyms. These include Balsamina, Canneta, Croattina, Guzetta, Guzitta, Guzzetta, Inzaga, Inzagre, Massana, Nespolina, Nespolino, Novarina, Solenga, Ughetta, Ughetta di Caneto, Ughetta di Canetto, Ughetta di Canneto, Ughetta di Fassolo, Ughetta di Solenga, Uva Cinerina, Uva Rara, Uvetta, Uvetto, Vespolino, Visparola and Vispavola. Vespolina Vespolina is a red Italian wine grape variety that is planted in Piedmont around Gattinara
Petite mutation petite negative mutants. Potentially, these yeasts have a different inheritance system in place for their mitchondrial genome than "S. cerevisiae" does. The frequency at which "S. castellii" spontaneously produces petites is similar to that of "S. cerevisiae", with the mitochondrial DNA of those petites being highly altered via deletion and rearrangement. Suppressive petites of "S. cerevisiae" are the most commonly observed spontaneously created mutants, whereas in "S. castellii," the most commonly observed spontaneous mutant is the neutral petite, further leading to speculation that the transference of this mutation differs between species.
