IRAD is in the main governmental Agricultural Research Institute in Cameroon. Its
activities cover 5 domains namely: Annual crops, Perennial crops, Forest and Environment,
Animal and Fisheries and Farming Systems. 20 Research programmes are being conducted on
more than 30 IRAD research stations which are spread over 5 agro-ecological zones with
various rainfall patterns and soil types.
Dr. Charles THE is the Scientific Coordinator for Annual Crops. This domain includes
the 4 research programmes: Cereals; Root, Tubers, and Banana/Plantain; Leguminous crops
and Horticulture; and Industrial Annual Crop. He is experienced in coordinating complex
Networks such as the West and Central African Maize Network (WECAMAN, 1987-1992) and the
Conference des responsables de la recherche agricole an Afrique du centre et de l'ouest
(CORAF) since 1992. Dr. Charles THE graduated (PhD) in plant breeding and genetic at the
North Dakota State University (U.S.A.) in 1983. Since then he has been involved in
breeding for stress tolerance including drought tolerance, striga tolerance, acid soil
tolerance, and tolerance to low N supply. For his contributions, in April 1997 he received
a Certificate of Merit from WECAMAN (West and Central African Maize Network sponsored by
USAID) for outstanding contribution towards Maize research and development in West and
Dr. THE started working on soil acidity related problems in 1988. His main achievements
include the development of ATP-SR (Acid-tolerant, streak virus-resistant population). From
this population 8 synthetic varieties and 50 inbred lines with added level of acid soil
tolerance have been extracted and tested in neighboring countries as well as modern
laboratories in Europe. Dr. C. THE's recent participation at a Molecular Biologie
symposium at IITA Ibadan Nigeria, from August 16-17, 1999 on the application of molecular
markers in plant breeding would allow him to strengthen interaction with the Mol.
Biologists in the programme.
The scientific group in the maize programme includes breeders, agronomists and soil
scientists which allow IRAD not only to take over responsibilities in the area of plant
improvement but also in the area of Agronomy and Plant-Soil Interactions. The personnel
involved in the program will be: Dr. C. The PhD, Maize breeder, Dr. P. Zekeng PhD,
Agronomist, Dr. J. Tonye PhD, Farming system Agronomist, Dr. L. Enyong PhD, Social
Economist, Mr. Ambassa-Kiki MSc., Soil Scientist, Mr. C. Zonkeng MSc., Maize Breeder, Mr.
A. Tagne MSc. Maize pathologist, Ms. A. Kingue, Technician, and Mr. M. Njume, Technician.
