Long-cycle crops play a fundamental role in Cameroon’s economy. They contribute to the creation of wealth and jobs (fight against poverty and mass unemployment), to the preservation of the environment (restoration of ecological balances especially in deforestation areas) and to the diversification of agricultural production and sources of income. Research on Perennial Crops is conducted through four programs: Fruit Program, Stimulant Plants Program, Oilseed Plants Program (Oil Palm), and Latex Plant Program (Hevea). This Coordination aims to develop new standards and scientific innovations in order to boost production and thus increase the income of producers. It conducts research in genetics and develops appropriate cultivation methods and crop protection techniques.


Contribute in a sustainable way to the development of the different sectors of perennial crops through the improvement of crop varieties and technical itineraries adapted to local production conditions. Efforts also aim to support the policies and orientations defined by the public authorities in the field of perennial crops.

Research Programs

Stimulant crops (cocoa, coffee and colanuts)

The economic recovery in Cameroon necessarily involves improving the quantity/quality of agricultural production in certain pilot sectors, especially cocoa, coffee (robusta and arabica), colanuts, etc. and the competitiveness of the resulting products at sub-regional, regional and even international levels. To this end, the Stimulant Crops Program aims at strengthening the long-term sustainable agricultural performance of cocoa, coffee and colanut. Activities of this program also aim at ensuring better health through the enhancement of healthy and environmentally friendly use of agricultural inputs.

Fruit crops (citrus, mango, avocado, cashew etc.)

This program conducts research on improving the quality and quantity of fruit production for local and sub-regional markets. It also participates in the restoration of ecological balance and the provision of other environmental services in deforestation zones. It also contributes in the fight against poverty by diversifying the sources of income of the various actors.

Oilseed crops (oil palm, coconut)

This program aims at improving the production of long-cycle oilseed crops by developing improved planting material. The activities carried out are: the selection and dissemination of high yielding and disease tolerant plants with early maturity, slow-growth, low levels of acidity and saturated fatty acids in oil. The Program also develops appropriate technical itineraries and fertilizer application recommendations.

Latex plants (rubber tree)

The activities of this Program include:

  • Vegetative propagation and dissemination of improved plant material;
  • Soil characterization for rubber cultivation;
  • Development of technical itineraries suitable for rubber exploitation;
  • Integrated management of pests and diseases;
  • Quality control of latex and granulated rubber.

Salient Results


  • More than 150 clones available in our collections including 15 hybrids tolerant to brown rot;
  • Development of integrated disease and pest management strategies.


  • More than 300 genotypes of Arabica coffee and 200 Robusta available;
  • Reference systems for alternative regeneration techniques developed;
  • Integrated pest and disease management strategies developed;
  • A variety of Arabica coffee tolerant to the main diseases and pests selected.


  • More than 150 clones and accessions available;
  • A reference system developed for the early selection of rubber trees;
  • appropriate technical itineraries for rubber exploitation developed;
  • A system of discriminatory fertilizer use assessment elaborated, validated and disseminated.

Oil palm

  • More than 2 million germinated Fusarium-tolerant seeds produced annually;
  • Improved yields by more than 36% in two selection cycles of the Tenera hybrid;
  • Development of 14 categories of high-yielding second cycle Tenera hybrid with early maturity and reduced growth rate.

Fruit Tress

  • Fruit species and varieties (mango, citrus, guava, avocado, papaya, pineapple, safoutiers, cashew …) with high yields, tolerant to the main pests and diseases and adapted to the different agro-ecological zones introduced, selected and disseminated;
  • Integrated management strategies for major diseases and pests developed.

On-going Projects


  • Future research activities will focus on strategies for controlling emerging diseases and pests and developing varieties that are resilient to climate change.
  • Sustainable intensification of agriculture through integrated management of soil fertility;
  • Valorization of research results by the production of quality planting material in sufficient quantity to meet the ever increasing local and international demand;
  • Training and capacity building of newly recruited researchers;
  • Research on new species of economic interest (cashew, date palm, green pepper, ornamental horticulture …).
