Breeding for enhanced zinc and iron concentration in CIMMYT spring wheat germplasm
Micronutrient malnutrition, resulting from dietary deficiency of important minerals such as zinc (Zn) and iron (Fe), is a widespread food-related health problem. Genetic enhancement of crops with elevated levels of these ...
Breeding adult plant resistance to stripe rust in spring bread wheat germplasm adapted to Sichuan Province of China
Sichuan is an important wheat producing province of China where severe stripe rust epidemics occur annually. Developing high-yielding wheat varieties with good and stable stripe rust resistance is a foremost breeding ...
Genetic gains for grain yield in CIMMYT spring bread wheat across international environments
The Global Wheat Program of the International Maize and Wheat Improvement Center (CIMMYT) develops and distributes improved germplasm targeted toward various wheat growing regions of developing world. The objective of our ...
Identification and characterization of international Fusarium head blight screening nurseries of wheat at CIMMYT, Mexico
Fusarium head blight (FHB) is a major threat to wheat production globally, causing not only yield losses but also food and feed contamination. FHB research began at the International Maize and Wheat Improvement Center ...
Lr68: a new gene conferring slow rusting resistance to leaf rust in wheat
The common wheat cultivar Parula possesses a high level of slow rusting, adult plant resistance (APR) to all three rust diseases of wheat. Previous mapping studies using an Avocet-YrA/Parula recombinant inbred line (RIL) ...
Races of Puccinia graminis f. sp. tritici with combined virulence to Sr13 and Sr9e in a field stem tust screening nursery in Ethiopia
North American durum lines, selected for resistance to TTKSK (Ug99) and related races of Puccinia graminis f. sp. tritici in Kenya, became susceptible in Debre Zeit, Ethiopia, suggesting the presence of stem rust races ...
Identification and mapping of leaf, stem and stripe rust resistance quantitative trait loci and their interactions in durum wheat
Leaf rust (Puccinia triticina Eriks.), stripe rust (Puccinia striiformis f. tritici Eriks.) and stem rust (Puccinia graminis f. sp. tritici) cause major production losses in durum wheat (Triticum turgidum L. var. durum). ...
The emergence of Ug99 races of the stem rust fungus is a threat to world wheat production
Race Ug99 of the fungus Puccinia graminis tritici that causes stem or black rust disease on wheat was first detected in Uganda in 1998. Seven races belonging to the Ug99 lineage are now known and have spread to various ...
