Small-scale, precise inoculation of wheat seedlings with stem rust
Demonstrating the small-scale, precise inoculation by spraying of wheat seedlings with stem rust using a stored spore sample in the laboratory, at the Njoro research station, part of the Kenya Agricultural Research Institute (KARI).
The demonstration was carried out by Matthew Rouse, a PhD student at the University of Minnesota, working with the USDA. It was part of a two-week international training course on “Stem Rust Note Taking and Evaluation of Germplasm” hosted by KARI at Njoro from 28 September to 7 October 2009. The course was attended by scientists from over 20 countries, many of whom are collaborators with the Borlaug Global Rust Initiative (BGRI). It was jointly organized by CIMMYT, the Durable Rust Resistance in Wheat Project, KARI, and the International Center for Agricultural Research in the Dry Areas (ICARDA).
Njoro is home to an ongoing screening program, working in close partnership with CIMMYT to identify sources of resistance to the Ug99 race of stem rust. This virulent new strain of the disease, which emerged in Uganda in 1999, is already endemic in the area, making it possible to use Njoro as a testing ground for wheats from many different partner countries all over the world. More than 30,000 wheat lines are now being screened each year.
