NA 8 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: river NAnay.
Collected by Pound.
Location: R. Nanay, Peru.

Pound, 1938a [POU38A]. Fruit - unpigmented, half blanco, long oval, slightly warty, no conspicuous point nor bottle neck. Bartley, 1995a [BAR95A]. Pound describes the typical NANAY as above (pod colour between light/intermediate green) but fruits with different characteristics appear among the NA clones of today which result from seedling progenies of the original collections. Posnette, 1945a [POS45A]. Fan branches are characterised by relatively short (less than 2 cm) petioles in which the pulvini are not clearly separated until the leaf ages, when a shallow constriction may develop. The stamen filaments are always pigmented to some degree, usually heavily.

Notes: Collected in 1937.

Pound, 1938a [POU38A]. Pods were probably collected from 14 trees which were free of witches' broom disease.

Pound, 1943b [POU43B]. 708 plants were planted at Marper farm.

Notes

Trinidad - Marper Farm, University of the West Indies Datafile: DIS_WBDS - Disease reaction to Witches' Broom Experimental Conditions: Budded seedling progeny were established at Marper Farm, Trinidad in 1939-41 after quarantine in Barbados. By the time of this report (1943) the 1939 planted trees stand 15 ft. high, span 8ft. and have borne 20-30 pods. The oldest trees have been checked for incidence of Witches' Broom infection for three consecutive years and in 1943 were classified for resistance on the field observation basis. A tree was classified as resistant if it had less total brooms per annum than it had years of age. For example, a well-developed three year old tree with a total of less than 6 brooms or less than 3 brooms during its third year would be selected. Disease - Crinipellis perniciosa (Marasmius perniciosa), (Local Names: Witches' Broom Disease, Escoba de bruja, Balai de sorciere, Vassoura de bruxa).
