Abstract

Twenty eight lines or cultivars of diploid (genomes A, D, S-I, U), tetraploid (genomes AB, (DMv)-M-v, UM, USv), and hexaploid (genome ABD) wheat were studied for their capacity to sustain the development of nine populations of Heterodera avenae originating from six countries (Algeria, France, Spain, Australia, India, and Israel), two populations of Heterodera filipjevi from Russia and Bulgaria, and one population ofHeterodera latipons from Israel. Screenings were performed in artificial conditions using miniaturized tests. High resistance against Populations of H. avenae sensu stricto occurred in the three levels of ploidy and in several genomes: S-I (T. longissimum), (DMv)-M-v (T. ventricosum), UM (T. ovatum), USv (T. variabile), and ABD (T. aestivum AUS 4930). Total or intermediate resistance was found in genome D (T. tauschii CPI 110813 or AUS 18913) but their expression in synthetic hexaploid wheat was incomplete resistance. It was confirmed that the Cre1 genefrom wheat cv. Lores is ineffective against H. avenae populations from Australia, India, and Israel but also against H. filipjevi. Inter- and intraspecific differentiation within the cereal cyst nematode complex, based on (a)virulence to Triticeae and fitness, and the use of total and intermediate resistance in breeding programmes are discussed.
