Landraces are considered a valuable source of potential genetic diversity that could be used in the selection process any plant breeding program. Here, we assembled population 600 bread wheat landraces collected from eight different countries, conserved at ICARDA's genebank, and evaluated structure using single nucleotide polymorphism (SNP) markers. A total 11,830 high-quality SNPs distributed across genomes (40.5%), B (45.9%), D (13.6%) were for final analysis. The analysis was model-based...
A wheat rust survey was conducted in Iraq 2019 and collected 27 stem (caused by Puccinia graminis Pers.:Pers. f. sp. tritici Erikks. & E. Henn.) samples. Seven samples were viable, they tested for races of P. at the Regional Cereal Rust Research Center (RCRRC) Izmir, Turkey under strict quarantine procedures. Two 0.5 cm segments each infected sheath incubated a petri dish 20°C three hours re-hydration urediniospores, which multiplied on 10-day old seedlings susceptible cultivar Morocco grown...
Stripe or yellow rust, caused by Puccinia striiformis Westend. f. sp. tritici is a major threat to bread wheat production worldwide. The breakdown in resistance of certain genes and newly emerging aggressive races stripe rusts pose serious concerns all main growing areas the world. To identify new sources associated QTL for effective utilization future breeding programs an association mapping (AM) panel comprising 600 landraces collected from eight different countries conserved at ICARDA...
Landraces are a potential source of genetic diversity and provide useful resources to cope with the current future challenges in crop breeding. Afghanistan is located close centre origin hexaploid wheat. Therefore, understanding population structure Afghan wheat landraces enormous importance breeding programmes for development high-yielding cultivars as well broadening base bread Here, panel 363 collected from seven north north-eastern provinces were evaluated using single nucleotide...
Stripe rust caused by Puccinia striiformis Westend. f. sp. tritici . is a major bread wheat disease worldwide with yield losses of up to 100% under severe pressure. The deployment resistant cultivars adult plant resistance the provides long-term solution stripe wheat. An advanced line from International Winter Wheat Improvement Program (IWWIP) 130675 (Avd/Vee#1//1-27-6275/Cf 1770/3/MV171-C-17466) showed high level in field. To identify genes this elite line, mapping population 190 doubled...
Wheat rust diseases, including yellow (Yr; also known as stripe rust) caused by Puccinia striiformis Westend. f. sp. tritici, leaf (Lr) triticina Eriks. and stem (Sr) graminis Pres tritici are major threats to wheat production all around the globe. Durable resistance diseases can be achieved through genomic-assisted prediction of resistant accessions increase genetic gain per unit time. Genomic (GP) is a promising technology that uses genomic markers estimate breeding values (GBEVs) for...
Over the last decade, field assessments of yellow rust differential lines for resistance genes Yr10 and Yr24 race analysis in Middle East have demonstrated efficient control by (=Yr26). Yellow samples collected during 2018-21 Central West Asia & North sub-Saharan Africa underwent at Regional Cereal Rust Research Center Izmir, Türkiye. The infected leaf segments were subjected to rehydration 20°C three hours. Subsequently, rubbed on first leaves seedlings susceptible cultivar Morocco....
Stripe rust is among the most destructive foliar diseases affecting wheat globally. The identification of novel adult plant resistance loci represents a critical strategy for mitigating substantial yield losses attributed to stripe across diverse regions worldwide. Wheat landraces possess untapped genetic resources abiotic and biotic stresses including like rust. This study was conducted identify basis response in bread landrace BWLR-2347 conserved at ICARDA gene bank. mapping population 178...
