This study characterized and evaluated a set of wheat-Aegilops comosa introgression lines, including six additions and one substitution. A total of 47 PLUG markers and a set of cytogenetic markers specific for Ae. comosa chromosomes were established after screening 526 PLUG primer pairs and performing FISH using oligonucleotides as probes. Marker analysis confirmed that these lines were wheat-Ae. comosa 2M–7M addition lines and a 6M(6A) substitution line. The molecular and cytogenetic markers developed herein could be used to trace Ae. comosa chromatin in wheat background. In order to evaluate the breeding value of the material, disease resistance tests and agronomical trait investigations were carried out on these alien chromosome introgression lines. Disease resistance tests showed that chromosomes 2M and 7M of Ae. comosa might harbor new stripe rust and powdery mildew resistance genes, respectively, therefore, they could be used as resistance sources for wheat breeding. Investigations into agronomical traits showed that all chromosomes 2M to 7M had detrimental effects on the agronomic performance of wheat, therefore, the selection of plants with relatively negative effects should be avoided when inducing wheat-A. comosa chromosome translocations using chromosome engineering procedures.

“…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

Utilization of deletions to localize a gene for resistance to the cereal cyst nematode, Heterodera avenue, on an Aegilops ventricosa chromosome

et al. 1996

A previous RFLP analysis showed that the Aegilops ventricosa chromosome 6M^ which compensates for the absence of 6D in 6M^ (6D) wheat substitution lines was a 2/6 translocated chromosome, either 2S-6S.6L or 2S-6L.6S. The distal part of its long arm consists of a translocated segment belonging to homoeologous group 2. Chromosome 6M^ carries a gene(s) for resistance to cereal cyst nematode. In order to define the part of 6M^ (2S or 6S or 6L) involved in this resistance, addition lines with a 6M^ deleted either for its short arm or for the distal part of its long arm were evaluated. It was shown that the gene(s) is carried by the group 2 translocated segment. The hypothesis that the gene(s) could be allelic to Cre2, another gene conferring resistance to the nematode introduced into the wheat complement from Ae. ventricosa is discussed.
