Genome-wide association mapping for resistance to leaf rust, stripe rust and tan spot in wheat reveals potential candidate genes
(Springer Verlag, 2018)
Leaf rust (LR), stripe rust (YR) and tan spot (TS) are some of the important foliar diseases in wheat (Triticum aestivum L.). To identify candidate resistance genes for these diseases in CIMMYT?s (International Maize and ...
Adult plant resistance to stem rust (Puccinia graminis f. sp. tritici) in Pakistani advanced lines and wheat varieties
(Southern Cross Publishing, 2018)
After decades of effective wheat stem rust control, due mainly to use of the Sr31 resistance gene in wheat, as of the early 2000s new virulent strains of the stem rust fungus, especially the Ug99 or the TTKSK races, are ...
Harnessing diversity in wheat to enhance grain yield, climate resilience, disease and insect pest resistance and nutrition through conventional and modern breeding approaches
(Frontiers Media, 2016)
Current trends in population growth and consumption patterns continue to increase the demand for wheat, a key cereal for global food security. Further, multiple abiotic challenges due to climate change and evolving pathogen ...
Suppression expression of resistance to stripe rust in synthetic hexaploid wheat (Triticum turgidum x T. tauschii)
Some 74 hexaploid wheats, synthesized by either crossing resistant Triticum turgidum var. durum [T. durum] with susceptible/intermediate T. tauschii [Aegilops squarrosa] or susceptible/intermediate T. turgidum with resistant ...
Wheat rusts and the costs of genetic diversity in the Punjab of Pakistan
The theory of impure public goods is used to demonstrate why farmers may nor grow wheat cultivars with the socially desirable level of rust resistance. First, they may grow cultivars that are high yielding though susceptible ...
Agronomic effects from chromosome translocations 7DL.7Ag and 1BL.1RS in spring wheat
In hexaploid wheat (Triticum aestivum L.) disease resistance genes transferred hom alien sources are often associated,vith undesirable traits. Replicated trials using near-isogenic lines of spring wheat 'Seri 82' were ...
CIMMYT's approach to breeding for wide adaptation
The wheat area in developing countries, including China, is around 100 million ha. To address the needs of these very diverse wheat growing areas, CIMMYT has defined 12 wheat mega-environments (ME). A ME is defined as ...
