Non-Authenticity of Spring Barley Genotypes Revealed in Gene Bank Accessions

Plants, 2022
Plant research and breeding depends on plant genotypes; therefore, genotype authenticity of accessions is the basic requirement for users of gene banks. Surprisingly, this extremely important topic is rarely reported in the scientific community.

Response of Ten Egyptian Wheat Cultivars to Infection by Stem Rust and Postulation of Resistance Genes [PDF]

Egyptian Journal of Phytopathology, 2013
Stem rust has been one of the most serious diseases on wheat in Egypt, particularly on the late sowings. The locally produced wheat cultivars have been developed as field resistant to stem rust regardless their reaction in terms of infection types.

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.

Multi-Pathotype Testing of Selected Kenyan Wheat Germplasm and Watkin Landraces for Resistance to Wheat Stripe Rust (Puccinia striiformis f. sp tritici) Races

Agronomy, 2019
Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the key diseases of economic importance in wheat worldwide. Host resistance, which follows the gene-for-gene hypothesis between the host and pathogen, has been used in ...

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.

Identification of leaf rust resistance genes i n selected Argentinean bread wheat cultivars by gene postulation and molecular markers

Electronic Journal of Biotechnology, 2011
Leaf rust, caused by Puccinia triticina Eriks. is a common and widespread disease of bread wheat ( Triticum aestivum L.), in Argentina. Host resistance is the most economical, effective and ecologically sustainable method of controlling the disease.
