GU 255 /P    Theobroma cacao

 French Guiana - CIRAD-CP (1994)
Morphological characteristics of the clones held at CIRAD Guyane.. Data supplied to ICGD on computer diskette. Dr. Ph. Lachenaud, CIRAD Guyane.

Collected by Clement/Salle IRCC.
Location: Haut Camopi+Ecuador, GUF.

Lachenaud, 1993a [LAC93A]. Haut-Camopi material (See CAM 1, 3, 7, 9, 12) generally tall, Leaves - pigmented flushes, Fruit - heterogeneity in pod shape but usually green, clear basal constriction, obtuse apex, intermediate surface rugosity, prominent paired ridges.

Notes:  French Guiana - CIRAD-CP, 1994 [GUY94A] GU 112-359 from French Guiana, GU 360-370 from Ecuador.

Some publications have erroneously omitted the GU code and list only the clone number and suffix, for example 269H = GU 269/H and N 123 = GU 123/N.

2 May 2002 Data collected on wild trees from which the GU material were collected as seed has been removed from the ICGD on the recommendation of Philippe Lachenaud (CIRAD-CP). The descriptors referred only to the wild material which was never cloned in genebanks and as such the presence of these data were believed to be misleading. All GU material was collected as seed and properly labelled material should include a letter suffix at the end of the name.
