Identification of genes for leaf rust resistance in seedlings of wheat cultivars from the Yellow-Huai Basin in China and slow rusting observations in field trials

Czech Journal of Genetics and Plant Breeding, 2023
Wheat leaf rust is a devastating disease worldwide. Identification of leaf rust resistance genes in seedlings and of genes for slow rusting are important in resistance breeding and for gene deployment to control the disease.

Wheat leaf rust races/pathotypes in the Czech Republic in 1997-1998

Plant Protection Science, 1999
In 1997-1998 virulence of the wheat leaf rust population was studied on Thatcher near isogenic lines with Lr1, Lr2a, Lr2b, Lr2c, Lr3. Lr9, Lrll, Lrl5, Lrl7, Lrl9, Lr21, Lr23, Lr24, Lr26 and Lr28. On these NILs 11 pathotypes were determined in 1997, and 8

Mining Middle Eastern and Central Asian Barley Germplasm to Understand Diversity for Resistance to Puccinia hordei, Causal Agent of Leaf Rust

Agronomy, 2021
Vast collections of barley germplasm have been established and conserved in various global gene banks. These collections hold tremendous genetic diversity for resistance genes to Puccinia hordei, a causal agent of barley leaf rust.

Seedling and adult plant resistance to leaf rust in 46 Chinese bread wheat landraces and 39 wheat lines with known Lr genes

Journal of Integrative Agriculture, 2019
Wheat leaf rust, caused by Puccinia triticina (Pt), is an important foliar disease that has an important influence on wheat yield. The most economic, safe and effective way to control the disease is growing resistant cultivars.

A landscape-scale field survey demonstrates the role of wheat volunteers as a local and diversified source of leaf rust inoculum

Scientific Reports, 2023
Deploying disease-resistant cultivars is one of the most effective control strategies to manage crop diseases such as wheat leaf rust, caused by Puccinia triticina. After harvest, this biotrophic fungal pathogen can survive on wheat volunteers present at

Comparative transcriptomics of stem rust resistance in wheat NILs mediated by Sr24 rust resistance gene.

PLoS ONE, 2023
Stem rust of wheat is a deleterious fungal disease across the globe causing severe yield losses. Although, many stem rust resistance genes (Sr) are being used in wheat breeding programs, new emerging stem rust pathotypes are a challenge to important Sr ...

The identification of wheat leaf rust resistance genes and their utilisation value in 42 wheat cultivars

Czech Journal of Genetics and Plant Breeding
Leaf rust is an important wheat disease that considerably reduces the wheat production in most wheat growing regions worldwide. This study aimed to identify leaf rust resistance genes in 42 wheat varieties to find genetic sources with the broadest ...

Genetic and Phenotypic Diversity of European Triticale: GWAS of Yellow Rust Resistance and Agronomic Traits

Plant Breeding, EarlyView.
ABSTRACT Triticale (x Triticosecale Wittmack) is an interspecific hybrid of wheat and rye. It is a promising grain and forage crop that thrives in poorer soils and low‐input farming systems. It can serve as a viable alternative to traditional small grains such as wheat and barley, bringing diversity to crop rotations and enhancing biodiversity in ...

Genetic analysis and molecular mapping of leaf rust resistance genes in the wheat line 5R618

Czech Journal of Genetics and Plant Breeding, 2014
The wheat (Triticum aestivum L.) line 5R618, bred at the China Agricultural University, is resistant in the seedling stage to the majority of the current Chinese pathotypes of wheat leaf rust (Puccinia triticina).

GWAS and genomic prediction of crown rust resistance in the southern US elite oat (Avena sativa L.) germplasm

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Crown rust (CR), caused by Puccinia coronata f. sp. avenae, is a major constraint to oat (Avena sativa L.) production in the southern United States. We dissected the genetic architecture of CR resistance and assessed genomic prediction in 234 winter and facultative oat lines adapted to the southern United States.
