Striga Resistant Sorghum
UKZN Researchers have developed Sorghum varieties that are resistant to Striga. Striga is parasitic weed and one of the major biotic constraints limiting production and productivity in Africa in cereal crops including maize, sorghum, pearl millet, finger millet and rice. Yield losses of 30 to 90% have been reported regularly in the semi-arid regions of sub-Sharan Africa, including South Africa. Several recommended cultural, chemical and host resistance measures have been proposed by international experts, but have not been adopted by the affected farmers due to high cost of implementation, or the ineffectiveness of the proposed method.
