The CRIG cocoa germplasm collection with notes on codes used in the breeding programme at Tafo and elsewhere. Technical Bulletin, No. 10, Cocoa Research Institute, Tafo, Ghana. pp. 62.

Derivation: Imperial College Selections.
Location: ICTA, Trinidad and Tobago.

Notes:  Lockwood & Gyamfi, 1979 [LOC79A] Selections from farms in Trinidad (1-100) and from Criollo progenies (101-107).

Cope, 1949a [COP49A]. One hundred selections were made as a result of a survey started in 1930 by Pound.

Bartley, 1993a [BAR93A]. Numbers 1 to 100 were selected from all over Trinidad, numbers 101 to 107 were Criollo trees selected from a farm but all have been lost and numbers greater than 111 are selections made in an experimental programme.

Bartley, 1996a [BAR96A]. The ICS material includes several clones which resulted from recent (at that time) introductions. These include Criollos from Nicaragua (ICS 60 and its relatives) or Venezuela. Other ICS clones represent "Amazonian" types originally introduced from the Orinoco. It is likely that several introductions were involved in creating the diversity that existed in Trinidad when Pound started the selection work.

Bartley, 1997b [BAR97B] From ICS 113 onwards these clones were used as parents in the AX / MX series. The same cross be known by an equivalent C [TTO] name.
