Sub-Saharan African farmers typically apply less than 20 kilograms of fertilizer per hectare of cropland — far less than their peers in any other region of the world. In 2014, partners in the Improved Maize for African Soils (IMAS) project developed 41 Africa-adapted maize varieties that respond better to low amounts of nitrogen fertilizer and are up for release in nine African countries through 24 seed companies.

To accelerate the breeding cycle and continually develop the improved wheat varieties needed to meet global needs, novel approaches are needed to extend conventional selection methods, said Dr. Jesse Poland, an assistant professor at Kansas State University and director of the Feed the Future Innovation Lab for Applied Wheat Genomics, in his presentation on “Genomic Selection and Precision Phenotyping” at the Borlaug Summit on Wheat for Food Security.
However, each new technology can only be effective in combination with others, meaning that the disciplines of genetics, physiology, engineering and bioinformatics must come together in order to advance on the fundamental concepts of breeding established by Dr. Norman Borlaug more than 50 years ago.
Scientists have made revolutionary advances in their ability to identify genes associated with traits such as drought tolerance or yield in the laboratory, but are still held back by the challenge of observing how these genes express themselves in a complex real-world environment, a practice known as phenotyping.
