Institute of Agricultural Research for Development, IRAD, Cameroon (Dr. Charles Thè)


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 the.jpg (12400 Byte)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 Central Africa.

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.
