The Southern African Development Community Wheat Yield Nursery (SADCWYN) was established by the Maize and Wheat Improvement Research Network (MWIRNET) for SADC in 1996 to distribute the best available bread wheat cultivars of the respective member countries to research and extension organizations in each country in the region. Three types of germplasm-targeted trials were decided on, viz. a dryland spring wheat, an irrigation spring wheat and a dryland winter wheat trial for evaluation in the corresponding macro-environments. Fifty-three trials were distributed to eleven SADC member countries in 1996 and fifty-five to ten of the eleven countries in 1997. In 1996 data response was received from 25 nursery locations, while only 18 nursery locations were reported on in 1997. The First and Second SADCWYN have however indicated not only substantial diversity in entries, but also considerable variation in grain yield potential and adaptability of varieties over fairly diverse environments. A detailed grain quality analysis was also performed on the entries from selected localities and this analysis similarly indicates considerable diversity among entries. While establishment problems have been experienced, the SADCWYN has already indicated that it can be of substantial benefit to SADC member countries, especially to those countries with limited breeding and research infrastructure and resources.
