The study evaluates the potential impacts of the Drought Tolerant Maize for Africa (DTMA) project run by CIMMYT and the International Institute for Tropical Agriculture (IITA) in 13 countries of eastern, southern and West Africa: Angola, Benin, Ethiopia, Kenya, Malawi, Mali, Mozambique, Nigeria, Tanzania, Uganda, Zambia, and Zimbabwe and Ghana.
This paper, published in Crop Science 50: 1-11, presents methodology
to prove within a high level of confidence if two samples of seeds are the same
genetic population or not, despite the difficulties involved in fingerprinting
heterologous populations. In addition to heterogeneity within populations,
difficulties can include sampling errors, differences in the fields or years in
which the seeds were multiplied, and seed mixing. Despite these confounding
sources of variation, the authors show the possibility to conclusively
differentiate each of the populations used in this work. This methodology
will allow breeders, seed companies, government agencies, and NGOs to ensure
the purity and identity of high-yielding, locally adapted OPVs reach farmers,
so they can generate the highest yields possible in their fields.
