Striga as a Constraint to Cereal Production in Sub-Saharan Africa and the Role of Host Plant Resistance
摘要
This chapter provides an overview on the biology of the parasitic weeds of the genus Striga, specifically S. asiatica and S. hermonthica, and their impact on three cereal staples of sub-Saharan Africa, maize, rice and sorghum. Host plant resistance to Striga mitigates the yield losses to these crops. Improvement of Striga resistance in these three crops is discussed including the possibility of expanding resistance sources through mutagenesis.
