History & Origin
A variety resistant to coffee leaf rust and coffee berry disease created at the Coffee Research Station (CRS; now the Coffee Research Institute, CRI) in Ruiru, Kenya. Batian was released in Kenya in 2010. Batian was created via single-tree selections from fifth filial (F5) generations from the male parent of some Ruiru 11 progenies. Batian is a composite variety, mixing three different pure line varieties. The varieties involved in the original crosses are: SL28, SL34, Rume Sudan, N39, K7), SL4 and the Timor Hybrid.
