The project “Hybrid wheat in Africa - increasing productivity and stability” will test several hundred hybrid spring wheat lines created with lines from major, global spring wheat regions such as Southern and Eastern Africa, the Americas, Australia and Europe. The test hybrids will be tested in 33 different environments on five continents over two years. This will test the hypothesis that geographically distant genepools can be exploited in wheat hybrids aiming at high, low and intermediate wheat production regions. Furthermore, extensive studies in Southern and Eastern Africa and Australia will investigate the perceived increased yield stability of wheat hybrids over traditional inbred varieties as stability of production is a key contributor to food security in developing countries. Finally, methods for cost-efficient hybrid seed production in South Africa will be tested with the aim of being able to produce affordable wheat hybrid seed locally.

“非洲杂交小麦——提高产量和稳定性”项目将测试数百个杂交春小麦品系，这些品系来自非洲南部和东部、美洲、澳大利亚和欧洲等全球主要春小麦产区。测试混合动力车将在两年内在五大洲的33个不同环境中进行测试。这将验证一个假设，即地理上遥远的基因库可以在针对高、低和中级小麦产区的小麦杂交中利用。此外，在南部和东部非洲以及澳大利亚进行的广泛研究将调查小麦杂交品种比传统自交系品种在产量稳定性方面的提高，因为生产稳定性是发展中国家粮食安全的关键因素。最后，将在南非测试具有成本效益的杂交种子生产方法，目的是能够在当地生产负担得起的小麦杂交种子。
