Résumé
Coffee Research started in Tanzania in 1934 when the coffee growers founded Lyamungu Research station, in the Kilimanjaro region.
The major achievements until 1960 where the selection of arabica varieties N39, H66, KP 162 and MP 423. Cultural practices were defined for these cultivars as well.
CBD and CLR became then major problems for the industry. Only genetic resistance could give a satisfactory reponse. Hybridisation and selection used Rume Sudan and Hibrido de Timer as main progenitors for resistance. Back crosses to commercial varieites provided adaptation and quality.
The final stage of selection is carried on before releasing the hybrids through vegetative propagation. An agronomic package is being studied fir this new planting material. This includes fertilisers requirements and pest control. Fungicides application for existing coffee are still under investaigation.
Clone and progeny selection of Robusta Coffee has been conducted at Maruku (Lake zone) since 1948. Five Robusta clones have been selected. They are currently being multiplied in Vegetative Propagation Units.
