“…1986; Dubin et al, 1989) The epidemic components included the latent period, the infection probability, the cumulative lesion sporulation, the lesion daily-expansion area and the parasitic fitness. In another study, twelve isolates of wheat powdery mildew with different sensitivities to temperature were tested using the detached leaf segment method at 18 o C and 22 o C, and there were significant differences among the epidemic components of the different isolates (Li et al, 2008).…”

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive foliar diseases affecting wheat in China. The use of resistant cultivars is the most economical, environment friendly, and effective means to control stripe rust. By means of gene postulation and pedigree analysis, the resistant genes to stripe rust in eighty-two wheat cultivars from the Fifty-six cultivars were resistant in the adult plant stage. Twenty-seven cultivars had slow-rusting characteristics. The cultivars that were resistant at all stages and the adult plant stage should be utilized widely.

“…The presence of Yr genes in the seedling stage was postulated by comparing the IT displayed by the cultivars with the IT of the known Yr gene testers. The pedigrees of the wheat cultivars were taken into consideration in the process of the gene postulation (Dubin et al, 1989). 22 (No.…”

“…Race designation according the binary notation proposed by Johnson et al (1972) Resistance genes such as Yr2, Yr3, Yr6, Yr7, Yr9 and YrA+ were widely used by CIMMYT during the seventies and eighties (Dubin et al 1989;Babebo et al 1990;Danial et al 1994) and have been deployed in commercial cultivars in Ecuador. Yr9 resistance derived from rye has been introduced in CIMMYT material through the 1B/1D translocation (Zeller 1973).…”

Virulence of wheat yellow rust races and resistance genes of wheat cultivars in Ecuador

2006

Virulence factors of the yellow rust, Puccinia striiformis, populations in bread wheat were studied in Ecuador between 1973 and 2004. The number of virulence factors has increased markedly from very few in the early seventies to 16 at the end of the 90s. Isolates belonging to race 0E0 seem to be the ancestor of a rapid virulence evolution of yellow rust in Ecuador. This evolution can be explained by a single step mutation pattern. Virulence to the resistance genes Yr1,

“…Infection types (ITs) were scored at 14 days after inoculation (Roelfs et al 1992). Plants with ITs of 0 to 2 were considered resistant, while those with ITs of 3 to 4 were considered susceptible (Dubin et al 1989).…”

Shi L., Li Z., Wang X., Kang Z., Zhu L., Ren Z., Li X., Liu D. (2016): Genetic analysis and molecular mapping of a leaf rust resistance gene in the wheat line 19HRWSN-129. Czech J. Genet. Plant Breed., 52: 1-5.The wheat (Triticum aestivum L.) line 19HRWSN-129 from CIMMYT showed resistance to the major Puccinia triticina (Pt) races collected in China. A 144 F 2:3 population was generated by crossing the resistant line 19HR-WSN-129 with the susceptible line Zhengzhou5389. All the F 2:3 plants were phenotyped by inoculating with the Pt race PHGN in the greenhouse. Segregation analysis indicated the presence of a single dominant gene conferring resistance to leaf rust in the wheat line 19HRWSN-129, temporarily designated as Lrshi. Using molecular markers, we mapped this resistance locus on chromosome 7BL. It was closely linked to the SSR markers Xgwm344 and Xcfa2040 with genetic distances of 2.8 cM and 1.4 cM, respectively. Compared with other chromosome 7BL-located leaf rust resistance genes (Lr14a, Lr14b, Lr68), we demonstrate, that Lrshi is a novel wheat leaf rust resistance gene.
