Wheat mutants showing altered adult plant disease resistance
Euphytica, 2001Wheat mutants, selected on an altered resistance phenotype to Puccinia striiformis f.sp. tritici, the causal agent of yellow rust, were assessed in greenhouse tests to determine the growth stage at which the mutant phenotype was expressed and which components of yellow rust resistance were altered.

Analysis of quantitative adult plant resistance to blackleg in Brassica napus
Molecular Breeding, 2019Leptosphaeria maculans L. causing blackleg is a highly evolved fungal pathogen that damages the rapeseed industry in Canada, Australia, and Europe. Advanced backcross populations segregating for intermediate resistance (BLMR2) and susceptible (blmr2) alleles were planted and inoculated using cotyledons.

Components of adult plant resistance to leaf rust in wheat
Euphytica, 1993Winter wheat genotypes were tested for resistance in the field by assessing the percentage sporulating leaf area after infection with wheat leaf rust. The disease level in the first field trial was too low for selection. In the second field trial a low sporulating leaf area was found on several genotypes showing a susceptible infection type.

Adult-plant resistance to yellow rust in wild emmer wheat
Netherlands Journal of Plant Pathology, 1988Seventy-six entries of wild emmer, susceptible to a culture of yellow rust, race 39E134, in the seedling stage at a low temperature-profile, were tested with the same culture for field resistance at two locations in the Netherlands. While most entries were susceptible also in the adult-plant stage, 15 showed an intermediate or resistant infection-type ...

Inheritance of resistance to wheat yellow rust at adult plant stage
Archives Of Phytopathology And Plant Protection, 2013In order to investigate on inheritance and gene action for resistance to yellow rust, the resistant line C.B227 was crossed with the susceptible variety Avocet. Parents (P1 and P2) and the resulting F1, F2 and F3 generations were planted in a randomised complete block design with two replications in the field.

Adult-Plant Resistance to Powdery Mildew in Knox 62 Wheat
Cereal Research Communications, 2003Quantitative adult-plant resistance is an alternative for short-lived single major-gene resistance in the control of wheat powdery mildew caused by Blumeria graminis (DC) E.O. Speer. Cultivar ‘Knox 62’ is known to have adult-plant resistance to powdery mildew, but the relationship between the genes conferring its resistance and corresponding ...

Diallel Analysis of Adult‐Plant Resistance to Powdery Mildew in Wheat
Crop Science, 1994Adult‐plant resistance (APR) to powdery mildew [Blumeria graminis (DC.) E. O. Speer f. sp. tritici Em. Marchal] in wheat (Triticum aestivum L.) has been documented as being more durable than hypersensitive resistance. However, little is known about the inheritance and diversity of this resistance. Combining abilities and gene effects for APR to powdery

Evaluation of seedling and adult plant resistance to Puccinia hordei in barley
Euphytica, 2008The responses of 92 barley genotypes to selected Puccinia hordei pathotypes were assessed in greenhouse tests at seedling growth stages and in the field at adult plant growth stages to identify known and/or unknown resistances. On the basis of multipathotype tests, 35 genotypes were postulated to carry Rph1, Rph2, Rph4, Rph5, Rph12, RphCantala, alone ...

The effect on grain yield of adult plant resistance to mildew in oats
Annals of Applied Biology, 1977SUMMARYLines were selected from progeny of the crosses Maldwyn × Milford and Maldwyn × Sun II which consistently exhibited small and large amounts of mildew in similar situations. These are referred to as ‘low’ and ‘high’ mildew lines respectively. In small plot field trials conducted in 1971, 1972 and 1973 the low mildew lines produced substantially ...

Characterisation and mapping of adult plant stripe rust resistance in wheat accession Aus27284
Theoretical and Applied Genetics, 2018A new adult plant stripe rust resistance gene, Yr80, was identified in a common wheat landrace Aus27284. Linked markers were developed and validated for their utility in marker-assisted selection. Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is among the most important constraints to global wheat production.
