TSH 774    Theobroma cacao

 Shripat, C. (1996)
The Cocoa Breeding Programme of the Ministry of Agriculture, Land and Marine Resources, Trinidad. Presented at the International Workshop on The Utilisation of Genetic Resources of the ICGT, June, 1996. Cocoa Research Unit, Trinidad.

Derivation: Trinidad Selected Hybrids.
Collected by Cocoa Board.
Location: Trinidad and Tobago.

Notes:  Selections from mixed populations of Amazons and Trinitarios.

Shripat, 1996a [SHR96A]. Each Trinidad clone was labelled with a code composed of certain letters as a prefix (TS, TSA, TSH, TSAN, TSHN) followed by a number which runs consecutively from 500 upwards regardless of the letters. Thus, there are no two new clones with the same number.

(see also Bartley, 1997c [BAR97C] ).
