 In: Burnett, P.A. (ed.). World perspectives on barley yellow dwarf. Proceedings. Mexico, DF (Mexico). CIMMYT. 1990. p. 453-45691-013517Summary: The appearance of Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae) in South Africa in 1978 as a major pest of wheat led to a search for sources of resistance for use in breeding programs. Resistance was identified in Triticum monococcum L. but proved difficult to transfer to T. aestivum L. Recently renewed efforts were made to find sources of resistance in T. aestivum. Genotypes from the countries of origin of D. noxia were screened using a new greenhouse technique. Two T. aestivum entries were identified as resistant to D. noxia. Further tests revealed high levels of antibiotic and antixenotic resistance to D. noxia in both entries. A
