The name Chewaka was given to the upland rice (Oraiza sativa L.) variety with the pedigree of YIN LU20, which was developed by Bako Agricultural Research Center between 2011 and 2013. The Chewaka variety and the other pipeline upland rice genotypes were evaluated against the standard check (Superica-1) across six environments (Chewaka, Boneya, Bako and Guttin in 2011, and at Boneya and Bako in 2012) main cropping seasons. The variety Chewaka out-yielded the standard check (Superica-1) by about 83%. The variety also showed resistance to the rice blast disease and it was found to be stable over the tested locations. It was released by Bako Agricultural Research Center in 2013.
