Abstract only

Food security in Asia, Africa and many other countries is threatened by the devastating stem rust race Ug99. Therefore, an organized effort was made to replace current susceptible varieties with agronomically superior resistant varieties. The efforts included evaluation of newly developed resistant varieties, their pre-release seed multiplication and faster dissemination in south Asia and Africa. The organized activity was initiated in crop cycle 2008-09 in Afghanistan, Bangladesh, Egypt, Ethiopia, Nepal and Pakistan, although other countries such as Kenya, Iran and India also participated. The objective was to multiply seed of the resistant varieties to plant about 5% of the wheat area in each country to ensure sufficient quantity of seed to displace currently grown varieties. The common principle applied in each of the countries was, evaluation of new resistant potential varieties and pre-release seed multiplication of those found promising. The organized effort was successful as more than a dozen resistant varieties were released in the six countries and seed made available at the time of release was several times higher than the normal release systems. The results showed that new Ug99 resistant varieties possessed yield superiority over best popular varieties. Seed multiplication and distribution successfully led to increased confidence and capacity of participating countries to meet the challenge of the Ug99. The spill over effect appeared to benefit other countries in the region.
