RIM 68 [MEX] Group Name Theobroma cacao

Hunter, J.R. (1961)
The status of cacao variety improvement work in the Western Hemisphere. Cacao (Costa Rica) 4: pp. 1-16.

Derivation: Rosario Izapa Mexico.
Collected by del Arco & Spencer.
Location: Tuxclachico, Chiapas, Mexico.

Hunter, 1961a [HUN61A]. Fruit - Long, thin Soconusco type. Seed - white. Bartley, 1997a [BAR97A]. Most of the genotypes are very similar with regard to their vegetative and floral characteristics. The fruit shapes also show very little variation as do most other fruit characteristics. Most of these genotypes have fruit with a light green colour and the others have some degree of anthocyanin pigmentation.

Notes: Hunter, 1961 [HUN61A] Selections from Hda La Rioja. Selections from the Pacific coast with some MATINA genes.

In the original format of the name was composed of a number with "R" or "RIM" as suffix to that.

Costa Rica - CATIE Datafile: CATIE__DS CRI - CATIE 1 IMAGE_DS PROGENY_ Germplasm: Descriptor information is presented for 294 clones, 8 related species and on one hybrid. In addition, limited information on a further 119 clones is given. This germplasm is mainly of Latin American origin, including the United Fruit clones, UF, and genotypes from Mexico and Brazil. Environment: Each clone is represented in the collection by up to 10 trees planted in a single row. Spacing is usually 2m within the row and 3m between the rows, although parts of the collection are planted in a 2.2 x 2.2m grid. Fertilizer, N-P-K-Mg/Ca in the ratio 18:10:6:5, is applied four times a year at 150g per tree. Shade is provided in most of the collection by an almost complete closed cover of trees of Erythrina poepiggiana and Inga spp. spaced at 12 x 12m. Character data: Seed dry weight: sample is dried for 1.5 h at 130°C and cooled in a desiccator. Seed length, seed width, seed thickness: average of 5 seeds from 20 fruits. Fruit, wall thickness at ridge: fruits are transversally sectioned and the soft endocarp tissue removed. Fruit, ridge pair separation: mean ratio of the distance between ridges within a pair and the distances between the ridges of two different pairs. Leaf, flush colour: measured when leaves are 5cm long. Producitvity: values are given as: 1=very low - c. 40 pods harvested over 3 years; 3=low, 5=intermediate - c. 40 pods obtained from 3-4 harvests over 1 year; 7=high, 9=very high - c. 40 pods harvested at one time.
