SCA 19    Theobroma cacao

 Pound, F.J. (1938)
Cacao and Witchbroom Disease of South America with notes on other species of Theobroma. Archives of Cocoa Research 1: pp. 26-71.

Collected by Pound.
Location: Rio Ucayali, Peru.

Notes:  Pound, 1943b [POU43B]. 22 plants were planted at Marper farm.

Bartley, 1993a [BAR93A]. Fausto Coral said that SCA stands for Sabino Contamana. Bartley considers that it is likely that the material comes from the town known to Pound as Contamana (on the R. Ucayali) since these progenies are very similar to P 31 [POU] from this area. Miguel Aspiazu (who accompanied Pound in Ecuador) said SCA came from Sabino and this may have been misinterpreted as SCAVINA.

UK - CABI Bioscience, 1998 [CAB98A] During surveys of Theobroma and Herrania spp. along the Amazon and Ucayali rivers (Pucallpa-Iquitos) in Octobet 1998, the local guide provided some detailed information on the history of the region. It seems the origin of the Scavinas is near to Iquitos around the Nanay river, from a Hacienda owned by the ESCAVINO family. The farm goes back to the pre-1930's but most of it has now been destroyed as the river Nanay has changed its course. This story, and the corruption of the name, was confirmed by a respected Peruvian agronomist, Reynaldo Crespo, who worked in the region 40 years ago.

Synonyms: EET 302 [IMP], EET IMP 302, SCAVINA 19
