Abstract

Previous studies showed that the intermediate lever of resistance in breadwheat line 'VPM1' to pathotype Ha12 of the cereal cyst nematode could be conferred by an Aegilops ventricosa-derived gene, CreX, in chromosome arm 2AS, which also carries the rust resistance genes Yr17, Lr37 and Sr38. Near isogenic lines (NILs) differing for the presence and absence of the Ae. ventricosa-derived linked genes Yr17/Lr37/Sr38 were tested with cereal cyst nematode. Lines carrying Yr17 produced significantly fewer nematode cysts thanthe controls. An infested soil experiment produced better differentiation among resistant and susceptible genotypes. Susceptibility of 'Trident' indicated that linkage between CreX and Yr17 is incomplete. Microsatellite markers did not differentiate between 'Trident' and CreX-carrying genotypes. However, Xgwm636 (104) was associated with the presence of Yr17 in all six genetic backgrounds. Since none of the reported cereal cyst nematode resistance genes is located in chromosome 2AS, CreX was designated as Cre5.
