“…It has been claimed that CCN resistance in Ae. ventricosa is associated with chromosome 6M V (Dosba and Rivoal 1981;Rivoal et al 1986). The following markers of this chromosome were absent from H93-8 (data not shown): AcoM v l (Mena et al 1993) from the long arm, and Xpsrl67-E-6M V , Xpup28-H-6M V (Mena etal.…”

Transfer of resistance toHeterodera avenae, the cereal cyst nematode (CCN), by a "stepping-stone" procedure from the wild grassAegilops ventricosa to hexaploid wheat has been demonstrated. The number of nematodes per plant was lower, and reached a plateau much earlier, in the resistant introgression line H93-8 (1-2 nematodes per plant) than in the recipient H10-15 wheat (14-16 nematodes per plant). Necrosis (hypersensitive reaction) near the nematode, little cell fusion, and few, often degraded syncytia were observed in infested H93-8 roots, while abundant, well-formed syncytia were present in the susceptible H10-15 wheat. Line H93-8 was highly resistant to the two Spanish populations tested, as well as the four French races (Fr1-Fr4), and the British pathotype Hall, but was susceptible to the Swedish pathotypes HgI and HgIII. Resistance was inherited as though determined by a single quasi-dominant factor in the F2 generations resulting from crosses of H93-8 with H10-15 and with Loros, a resistant wheat carrying the geneCre1 (syn.Ccn1). The resistance gene in H93-8 (Cre2 orCcn2) is not allelic with respect to that in Loros. RFLPs and other markers, together with the cytogenetical evidence, indicate that theCre2 gene has been integrated into a wheat chromosome without affecting its meiotic pairing ability. Introduction ofCre2 by backcrossing into a commercial wheat backgroud increases grain yield when under challenge by the nematode and is not detrimental in the absence of infestation.

“…Susceptibility of the wheat parents T. persicum and cv.`Marne', indicated that the CCN resistance of`VPM1' was derived from Ae. ventricosa, which is resistant to pathotypes Fr1 (Ha41) and Ha12 (Dosba and Rivoal 1981). Jahier et al (1996) demonstrated that resistance to CCN was carried by the Ae.…”

Previous studies showed that the intermediate level of resistance in bread wheat 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 Yrl7, Lr37 and Sr38. Near isogenic lines (NILs) differing for the presence and absence of the Ae. ventricosa‐derived linked genes Yrl7/Lr37/Sr38 were tested with cereal cyst nematode. Lines carrying Yr17 produced significantly fewer nematode cysts than the 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.

“…Discovery of CCN resistance in wild related species of wheat would therefore be of great importance. Such efforts have been made in different regions of the world where CCN is present (Dosba and Rivoal, 1981; Rivoal et al, 1986; Eastwood et al, 1991; Singh et al, 1991; Bekal et al, 1998), resulting in identification of several genes for resistance to CCN (McIntosh et al, 2008). Identification of additional sources of resistance is needed to combat CCN in wheat in China since most of the known resistance genes are not effective against all pathotypes of Heterodera spp.…”

Cereal cyst nematode (CON) is becoming one of the important soii-borne pathogens in wheat {Tritioum aestivum L.) monocropping or wheatmaize {Zea mays L.)-wheat cropping systems of centrai China. Heterodera filipjevi (Madzhidov, 1981) Stelter, 1984 was recentiy recognized as a causai agent of CCN in China, but iittie information is avaiiabie on sources of resistance against this nematode species. The present study was initiated to determine the current status of resistance in wheat cultivars against H. filipjevi and to identify effective resources for improvement of CCN resistance in China. A 3-yr field study of CCN resistance that involved 174 wheat cuitivars or \Nheat-Thinopyrum derivatives was
