Summary A research and development program for improved and sustainable cultivation systems of cassava and for cassava based agribusiness chains doesn’t exist yet in Suriname. Knowledge of the different cassava varieties and the availability of the genetic material for research and multiplication purposes are required. This can be achieved by the collection, description, conservation and evaluation of the genetic material available in Suriname. CELOS will start up and manage ex situ field genebank of cassava at the experimental sites (Leysweg, Phedra, Tijgerkreek West).
Background BaCKGROUND:
In the Amazon region of Latin America, the centre of origin of cassava, processed cassava roots and foliage are used for human and animal nutrition as well as for many non food industrial applications. Many research efforts resulted in sustainable cultivation systems adapted to prevailing natural circumstances in the growing areas. Through natural and artificial selection, breeding, propagation and distribution schemes, growers are supplied with genetic material adapted to their habitat and with production characteristics that are aimed at. Great concern with and huge awareness of the value of collected accessions for actual and future breeding and propagation purposes, this plant genetic material is conserved in different kinds of germplasm banks .
In Suriname, sweet cassava varieties are grown especially, but not exclusively, in the coastal plains for ‘fresh’ consumption of the roots, after a simple peeling and kitchen preparation process. In the interior of the country, mainly bitter varieties grown in the ‘slash and burn system’ of the Amerindians and the Maroons provide them the essential staple food. Traditional dishes, free of cyanogenic glucosides, are prepared by extreme processing of the roots. Consumption of young leaves is also noticed.
A research and development program for improved and sustainable cultivation systems of cassava and for cassava based agri-business chains in Suriname is required. Making available the genetic material for research and propagation purposes is part of the first phase. This can be achieved by the collection, description, conservation and evaluation of cassava genetic material. CELOS started this conservation and evaluation process in July 2006
Objective GENERAL GOAL:
1. Socio-economic approach:
The development of the Surinamese cassava cultivation and processing sector has been stimulated and supported
2. Scientific approach:
The biological diversity of Manihot esculenta Crantz in Suriname and its potential use as feedstock for an agribusiness chain has been studied and described

SPECIFIC GOALS:
1. Cassava germplasm has been conserved in ex situ field genebanks at CELOS experimental fields
2. Morphological diversity between the conserved accessions, their agronomic values, specific composition and suitability properties for processing have been assessed
Setup and activities
(Expected) Results RESULTS AIMED AT:
1. Collected local available accessions and their passport data
2. Permanent well managed ex situ field genebanks at two locations
3. Assessed morphological and agronomical characteristics of the accessions at two levels: preliminary in the field genebank and further in variety field experiments
4. Data resulting from experiments or analyses on the suitability of certain accessions for the production of feedstock for specific industrial purposes
5. Compiled data of the accessions
