Examining wheat seedlings infected with Ug99 stem rust in screenhouse at Njoro

Wheat seedlings infected with the Ug99 race of stem rust in a screenhouse at the Kenya Agricultural Research Institute's (KARI) Njoro research station. CIMMYT works in close collaboration with KARI scientists on large-scale trials screening wheat lines for resistance to Ug99, the new and virulent strain of stem rust that emerged in Uganda in 1999. It is already endemic in the Njoro area, making it possible to use the station as a testing ground for wheats from all over the world; thousands are planted annually as part of an ongoing screening and breeding effort.
