IMC 102 Group Name 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.

Derivation: Iquitos Mixed Calabacillo (Mid Channel).
Collected by Pound.
Location: Iquitos, Peru.

Pound, 1938a [POU38A]. Main type - very large lagarta calabacillo pods, oval, very smooth, normal blanco. Seeds large, flat, losenge shaped. 'Hybrid group'-large pods, somewhat warty at stem end but smooth and round like calabacillo at the apex. Third group-small, oval, warty pods, dense flowering. Bartley, 1995a [BAR95A]. The common features of this group of clones are the high ovule numbers (65+) and a specific type of anthocyanin pigmentation in the stamens and base of the corolla. Posnette, 1945a [POS45A]. Petioles are of a type intermediate between those of Nanay (see NA) and Parinari (see PA) types; the constriction is usually short and narrow.

Notes: Pound, 1938a [POU38A]. Pods probably collected from at least two groups of trees which were free of Witches' Broom.

Bartley, 1995a [BAR95A]. They are probably the progenies of two trees, later propagated as the clones P 18 [POU] and P 21 [POU].

Pound, 1943b [POU43B]. 112 plants were planted at Marper farm.

Bartley, 1997a, [BAR97A] The progeny of the individual clones is not documented and it is important not to consider the IMC clones as one homogeneous group.
