Ruiru 11

An Arabica cultivar from Kenya, a dwarf form with resistance to CBB (coffee berry borer)  and CBD (coffee berry disease) : Ruiru 11 is named for the station at Ruiru, Kenya where it was developed in the ’70s and released in 1986. The initial test were with Hibrido de Timor (a cross between Arabica and Robusta, resistant to Coffee Leaf Rust) and Rume Sudan, an original coffee strain resistant to CBD, Coffee Berry Disease. Later they added SL-28 and SL-34 and K-7 inputs due to poor cup character of the early tests. The Robusta content of Ruiru 11 is still an issue, and the cup does not match the quality of the SL types.
