“…Growing resistant cultivars is the most economical and environmentally safe approach to eliminate the use of fungicides and to reduce production losses due to this disease. Up to now, 30 gene loci (Pm1-Pm30) for resistance to powdery mildew have been identified and located on different chromosomes (Järve et al 2000;Rong et al 2000;Liu et al 2002;Zeller et al 2002), of which the recessive resistance gene Pm5 was located on the long arm of chromosome 7B (Law and Wolfe 1966;Lebsock and Briggle 1974). Pm5 is widely contributed in the cultivars and landraces of China and Europe (Huang et al 1997a;Zeller et al 1998).…”

Powdery mildew, caused by Erysiphe graminis DM f. sp. tritici (Em. Marchal), is one of the most important diseases of common wheat world-wide. Chinese wheat variety 'Fuzhuang 30' carries the powdery mildew resistance gene Pm5e and has proven to be a valuable resistance source of powdery mildew for wheat breeding. Microsatellite markers were employed to identify the gene Pm5e in a F(2) progeny from the cross 'Nongda 15' (susceptible) x 'Fuzhuang 30' (resistant). The gene Pm5e was mapped in the distal region of chromosome 7BL. Seven microsatellite markers were found to be linked to the gene Pm5e, of which two codominant markers Xgwm783 and Xgwm1267 were relatively close to Pm5e with a linkage distance of 11.0 cM and 6.6 cM, respectively. It is possible to use the 136-bp allele of Xgwm1267 in 'Fuzhuang 30' for marker-assisted selection during the wheat resistance breeding process for facilitation of gene pyramiding. The mapping information in the present study provides a starting point for fine mapping of the Pm5 locus and map-based cloning to clarify the molecular structure and function of the different alleles at the Pm5 locus. A microsatellite linkage map of chromosome 7B was constructed with 20 microsatellite loci, nine on the short arm and 11 on the long arm. This information will be very useful for further mapping of agronomically important genes of interest on chromosome 7B.

A repressed level of recombination is typical for wide crosses not only in wheat, but also in other cereals (Faris et al 1998;Jä rve et al 2000;Lu et al 2002), and results in the formation of tight linkage groups separated by gaps of at least 40 cM. SIM analysis of the 'BC5' mapping population indicated that chromosomes 2B and 2D are important for the determination of adult plant resistance to leaf rust (Fig.…”

Detection of quantitative trait loci for leaf rust resistance in wheat––T. timopheevii/T. tauschii introgression lines

Advanced backcross QTL analysis was used to identify QTLs for seedling and adult plant resistance to leaf rust in introgression lines derived from a cross between the spring wheat cultivar 'Saratovskaya 29' and a synthetic allopolyploid wheat (T. timopheevii/T. tauschii). F 2 mapping populations involving two backcross selections ('BC5' and 'BC9' lines) were genotyped with microsatellite markers. Two significant QTL for adult plant resistance were identified in line 'BC5': one on chromosome 2B, but originating from chromosome 2G, explained 31% of the trait variance. The other, derived from T. tauschii and mapped to the short arm of chromosome 2D explained 19% of the trait variance. In the second line, one major seedling and adult plant resistance QTL was identified on chromosome 2B. Both QTL co-located to the same marker interval. Such introgression lines, resulting from the reconstruction of common wheat genome, are of interest both as initial material for breeding and improvement of current cultivars, and as a resource for the study of the interaction and transformation of genomes.

“…Hence, it is necessary to search for novel resistance genes in wheat breeding. Up to now, 30 major wheat powdery mildew resistance genes (Pm1-Pm30) have been reported (McIntosh et al 1998;Järve et al 2000;Peusha et al 2000;Rong et al 2000;Liu et al 2002), some of which were introduced from wheat relatives. Wild emmer, Triticum dicoccoides (2n = 4x = 28; genome AABB), is the progenitor of cultivated tetraploid and hexaploid wheat and has a great potential for wheat improvement (Nevo 1995;Nevo et al 2002).…”

The powdery mildew resistance has been transferred from an Israeli wild emmer (Triticum dicoccoides) accession "G-305-M" into common wheat by crossing and backcrossing (G-305-M/781//Jing 411*3). Genetic analysis showed that the resistance was controlled by a single dominant gene at the seedling stage. Among the 102 pairs of SSR primers tested, four polymorphic microsatellite markers (Xpsp3029, Xpsp3071, Xpsp3152 and Xgwm570) from the long arm of chromosome 6A were mapped in a BC(2)F(3) population segregating for powdery mildew resistance and consisting of 167 plants. The genetic distances between the resistance gene and these four markers were: 0.6 cM to Xpsp3029, 3.1 cM to Xpsp3071, 11.2 cM to Xpsp3152 and 20.4 cM to Xgwm570, respectively. The order of these microsatellite loci agreed well with the established microsatellite map of chromosome arm 6AL. We concluded that the resistance gene was located on the long arm of chromosome 6AL. Based on the origin and chromosomal location of the gene, it is suggested that the resistance gene derived from "G-305-M" is a novel powdery mildew resistance gene and is temporarily designated MlG.
