Leaf Rust and Stripe Rust Resistance Genes Derived from Aegilops Sharonensis

Euphytica, 2006
Linked leaf and stripe rust resistance genes introgressed into hexaploid wheat from Aegilops sharonensis provided protection in the seedling stage to a wide range of pathotypes of the two diseases. Monosomic and telosomic analyses showed that the resistance genes occur on wheat chromosome 6A.

Isolation and characterization of culturable endophytic bacterial community of stripe rust–resistant and stripe rust–susceptible Pakistani wheat cultivars

International Microbiology, 2018
In this study, endophytic bacteria isolated from root, stem, and leaf tissues of stripe rust-susceptible (Inqilab 91, Galaxy 2013, and 15BT023) and stripe rust-resistant (NARC 2011, Ujala 2015, TW1410) cultivars were identified and characterized. Abundance of endophytes was found in roots as compared with stems and leaves.

Variability of the Stripe Rust Pathogen

2017
The stripe rust pathogen, Puccinia striiformis, is highly variable. The variation has been studied for about 100 years based on virulence, for about 30 years based on molecular markers, and for about 10 years based on genome sequencing and functional genomics. Virulence characterization using host differential genotypes has identified a large number of

Spatial analysis of wheat stripe rust epidemics

Crop Protection, 1992
Abstract The distribution of wheat stripe rust infection was analysed using fit to frequency models, dispersion indices and the regression of mean crowding on mean density. Disease was measured as severity using a sample unit of ten consecutive tillers along a drill row, with a W sample pattern in the field and the regression relationship percentage ...

Integrated Control of Stripe Rust

2017
Stripe rust, caused by Puccinia striiformis, can be controlled by growing resistant cultivars, applying fungicides and through some cultural practices. As developing and growing resistant cultivars is the most preferred approach for control of stripe rust and a great body of knowledge has been obtained for resistance, the topic of resistance is ...

Sequential sampling for wheat stripe rust management

Crop Protection, 1992
Abstract The development of a sequential sampling plan for wheat stripe rust is reported, based on knowledge of spatial pattern, and predetermined action thresholds and confidence levels. The plan reduced fungicide applications while maintaining yield at four test sites.

Stripe Rust Epidemiology

2017
Stripe rust, caused by Puccinia striiformis, is a polycyclic disease and its epidemic is mainly dependent upon the disease development rate. Although the pathogen has a heteroecious macrocyclic lifecycle that consists of five spore stages, it almost completely reproduces asexually on its primary hosts of cereal crops and auxiliary hosts of wild grasses.

Genetic architecture of leaf rust and stripe rust resistance in European wheat

2022
Braunrost, verursacht durch Puccinia triticina, und Gelbrost, ausgelöst durch Puccinia striiformis f. sp. tritici, zählen zu den bedeutenden Pilzkrankheiten im Weizen und ihr Auftreten führt weltweit zu Ertragsverlusten. Da ständig neue virulente Rostrassen nachgewiesen werden, zielt die Resistenzzüchtung auf die Erzeugung von Sorten mit langlebiger ...

STRIPE RUST, PUCCINIA GLUMARUM, IN CANADA

Canadian Journal of Research, 1936
A study was made of the distribution of Puccinia glumarum (Schm.) Erikss. and Henn. in Canada, its specialization, host range, and reaction to environmental conditions. Unlike Puccinia graminis Pers., this rust has a limited distribution, being confined to British Columbia, Alberta, and the western half of Saskatchewan.

Effects of Stripe Rust on the Wheat Plant

Australasian Plant Pathology, 1995
Stripe rust of wheat caused by Puccinia striiformis f. sp. tritici reduced kernel mass and the number of kernels per head in field epidemics from 1984 to 1987 in southern New South Wales. These epidemics began at the stem elongation stage of growth in 1984 and at booting to heading stages in the other years.
