SC 6 [COL]    Theobroma cacao

 Hunter, J.R. (1961)
The status of cacao variety improvement work in the Western Hemisphere. Cacao (Costa Rica) 4: pp. 1-16.

Derivation: Seleccion Colombiana.
Location: Palmira, Valle, Colombia.

Notes:  Doak & Zambrano, 1961 [DOA61A] Collected in 1961.

Bartley, 1993a [BAR93A]. May be the same as MIRANDA in Soria, 1970a [SOR70A].

In previous versions of the ICGD the SPA [COL] clones were included as synonyms of the group SC [COL] (SC 57 - 76 inclusive). The synonymy has now been reversed as this material was originally described as SPA and is more widely known under this name, as advised by Dr. Bartley.


 

Synonyms: SCP 6 [COL], COLOMBIA 6 [COL], SCS 6 [COL]
