Abstract Wheat leaf rust is caused by Puccinia triticina ( Pt ), leading to serious wheat yield loss in the world. To study population structure and reveal transmission routes of eastern China, samples were collected from main wheat-producing areas April June 2020. Total 372 strains amplified 13 SSR makers a high level genetic diversity was revealed with 289 multi-locus genotypes (MLG) identifi...

Aim. To study the variability of intrapopulation structure causative agent wheat leaf rust ( Puccinia triticina Erikss.) on basis pathogenicity under influence combined fungicide Abacus Ultra, SE. Material and Methods. The studies were carried out in greenhouse complex Federal Research Center Biological Plant Protection winter variety Krasnodarskaya 99 which is susceptible to rust. material stu...

Leaf rust, caused by Puccinia triticina Eriks., is a common and widespread disease of wheat (Triticum aestivum L.) in Egypt. Host resistance is the most economical, effective, and ecologically sustainable method of controlling the disease. Molecular markers help to determine leaf rust resistance genes (Lr genes). The objective of this study was to identify Lr genes in fifteen wheat cultivars fr...

BACKGROUND The development of novel highly efficacious fungicides that lack cross-resistance is extremely desirable. Fenpicoxamid (Inatreq™ active) possesses these characteristics and is a member of a novel picolinamide class of fungicides derived from the antifungal natural product UK-2A. RESULTS Fenpicoxamid strongly inhibited in vitro growth of several ascomycete fungi, including Zymosepto...

ABSTRACT Leaf and stripe rusts, caused by Puccinia triticina and P. striiformis, respectively, are globally important fungal diseases of wheat that cause significant annual yield losses. A gene that confers slow rusting resistance to leaf rust, designated as Lr46, has recently been located on wheat chromosome 1B. The objectives of our study were to establish the precise genomic location of gene...

Wheat leaf rust, caused by Puccinia triticina Eriks., is a common and destructive disease of wheat worldwide. The durable rust-resistance gene Lr34 typically described as an adult plant resistance gene, which not expressed at the seedling stage normal greenhouse temperatures. However, when plants with are grown low temperatures, i.e. approximately 8°C. Lines cultivars demonstrate range response...

Wheat (Triticum aestivum L.) is grown throughout the winter time in Southern Brazil and turns out to be main agricultural crop at such a year season State of Paraná. However, growing foliar diseases significantly compromise commercial yields manner as justify application fungicides right control production fields. The aim current manuscript was assess impact different timings for fungicide (epo...

More than 50 leaf rust resistance (Lr) genes against the fungal pathogen Puccinia triticina have been identified in the wheat gene pool, and a large number of them have been extensively used in breeding. Of the 50 Lr genes, all are known only from their phenotype and/or map position except for Lr21, which was cloned recently. For many years, the problems of molecular work in the large (1.6 x 10...
