Inheritance of adult plant resistance to powdery mildew in swedes

Annals of Applied Biology, 1989
SummaryA complete diallel set of crosses, including selfs, was produced from 11 inbred lines of swedes and assessed for adult plant resistance to powdery mildew in a replicated field trial. The plants were inoculated with powdery mildew spores on 23 July 1987. Traces of mildew were visible on 3 August.

INHERITANCE OF ADULT PLANT RESISTANCE TO POWDERY MILDEW IN SOYBEANS

Canadian Journal of Genetics and Cytology, 1978
In greenhouse tests with Microsphaera diffusa Cke &Pk. on soybeans (Glycine max (L.) Merr.), adult plant resistance was found to be governed by a dominant gene, proposed as Rmd, with the recessive allele, rmd, resulting in susceptibility at all stages.

Seedling and Adult-Plant Resistance to Yellow Rust

2001
Resistance to stripe rust of 56 advanced wheat lines/varieties introduced from International Maize and Wheat Improvement Center (CIMMYT) was evaluated at seedling stage in greenhouse and at adult-plant stage in field. Three pathotypes 6E0A−, 70E16A+, and 134E134A+ were used in greenhouse and pathotype 134E134A+ in field.

Adult Plant and Partial Resistance of Wheat As Kinds of Durable Resistance to Rusts

1993
Reaction of wheat to two types of resistance (adult plant and partial /horizontal) to rusts, has been studied during the last ten years in Bulgaria. Evidence on the existence of typical adult plant resistance (susceptible type of reaction at seedling stage and resistance in the adult stage), is presented.

Histological and cytological characterization of adult plant resistance to wheat stripe rust

Plant Cell Reports, 2012
Wheat cultivar Xingzi 9104 (XZ) possesses adult plant resistance (APR) to stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). In this study, histological and cytological experiments were conducted to elucidate the mechanisms of APR in XZ.

Adult-plant resistance to Septoria tritici blotch in hexaploid spring wheat

Theoretical and Applied Genetics, 2015
New QTL for Septoria tritici blotch detected in hexapoid spring wheat under field conditions across diverse environments. Septoria tritici blotch caused by the ascomycete fungus Zymoseptoria tritici presents a serious and consistent challenge to global wheat production.

Origin of leaf rust adult plant resistance gene Rph20 in barley

Genome, 2012
Rph20 is the only reported, simply inherited gene conferring moderate to high levels of adult plant resistance (APR) to leaf rust ( Puccinia hordei Otth) in barley ( Hordeum vulgare L.). Key parental genotypes were examined to determine the origin of Rph20 in two-rowed barley.

Mapping Rph20: a gene conferring adult plant resistance to Puccinia hordei in barley

Theoretical and Applied Genetics, 2011
A doubled haploid (DH) barley (Hordeum vulgare L.) population of 334 lines (ND24260 × Flagship) genotyped with DArT markers was used to map genes for adult plant resistance (APR) to leaf rust (Puccinia hordei Otth) under field conditions in Australia and Uruguay.

The identification of QTLs for adult plant resistance to leaf scald in barley

Australian Journal of Agricultural Research, 2006
Barley leaf scald disease, caused by the fungal pathogen Rhynchosporium secalis, can be economically damaging, causing both yield losses and lower quality from reduced grain size. Most genetic studies of scald resistance have concentrated on seedling reactions either because of a lack of access to field screening resources or else because of the more ...

Identification of wheat genotypes with adult plant resistance to powdery mildew

Cereal Research Communications, 2006
As in the case of other wheat diseases, adult plant resistance (APR) to powdery mildew remains effective longer than monogenic hypersensitive resistance, so the objective was to identify winter wheat genotypes with this type of resistance. Field and greenhouse tests conducted on 41 varieties and breeding lines indicated that 36 were susceptible in the ...
