Abstract only

Striga hermonthica is a devastating parasitic weed in sub-Saharan Africa, It infects the root systems of agriculturally important cereals acquiring water and solutes, through a specialised organ, the haustorium, Severe infestations can result in total grain failure. Complete resistance to S.hermonthica infection has not been identified for cereals, however, there is increasing evidence to suggest that near relatives of cereals may provide new sources of resistance. The aim of this work was to evaluate the susceptibility of a wild relative of maize, Tripsacum dactylodes, to S. hermonthica infection compared with susceptible maize and to determine the characteristics of a maize tripsaum hybrid in response to infection.
