The white grape variety originates from Spain. Synonyms are Chelva de Cebreros, Chelva de Guareña, Eva, Forastera Blanca, Gabriela, Guarena, Mantúa, Mantúo (2nd main name), Mantúo de Pilas, Mantúo Vigiriego, Montúa, Montúo de Villanueva, Montúo Gordo, Uva Rey or Uva del Rey, Uva de Puerto Real, Vigiriego Blanco and Villanueva. The varieties Mantúo or Montúa, previously assumed to be independent, are identical according to DNA profile comparison. It should not be confused with the varieties Beba (Chelva), Dona Branca, Doradilla, Forastera or Vijariego, despite seemingly indicating synonyms or morphological similarities. According to DNA analyses carried out in 2020, the variety originates from a presumably natural cross between Hebén x Dedo de Dama. However, this is based on only 20 DNA markers (see molecular genetics).
