Genetic mapping of resistance in hexaploid wheat for a quarantine disease
(Frontiers; Frontiers Media, 2018)
Karnal bunt (KB) of wheat, caused by Tilletia indica, is one of the greatest challenges to grain industry, not because of yield loss, but quarantine regulations that restrict international movement and trade of affected ...
Genetic gains for grain yield in CIMMYT’s semi-arid wheat yield trials grown in suboptimal environments
(Crop Science; Crop Science, 2018)
Wheat (Triticum aestivum L.) is a major staple food crop grown worldwide on >220 million ha. Climate change is regarded to have severe effect on wheat yields, and unpredictable drought stress is one of the most important ...
Genome-wide association study reveals novel genomic regions associated with 10 grain minerals in synthetic hexaploid wheat
Synthetic hexaploid wheat (SHW; Triticum durum L. × Aegilopstauschii Coss.) is a means of introducing novel genes/genomic regions into bread wheat (T. aestivum L.) and a potential genetic resource for improving grain mineral ...
Adult plant resistance to stem rust (Puccinia graminis f. sp. tritici) in Pakistani advanced lines and wheat varieties
(Southern Cross Publishing; Southern Cross Publishing-Australia, 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 ...
Relationship between the number of partial resistance genes and the response to leaf rust in wheat genotypes
(SciELO; Instituto de Investigaciones Agropecuarias,INIA, 2018)
The adult plant resistance conferred by genes with an additive effect is an alternative to achieve durable resistance to leaf rust caused by the fungus Puccinia triticina in wheat (Triticum spp.) The objective of this study ...
The performance of early-generation perennial winter cereals at 21 sites across four continents
A network of 21 experiments was established across nine countries on four continents and spanning both hemispheres, to evaluate the relative performance of early generation perennial cereal material derived from wheat, ...
Applications of machine learning methods to genomic selection in breeding wheat for rust resistance
(Crop Science Society of America, 2018)
New methods and algorithms are being developed for predicting untested phenotypes in schemes commonly used in genomic selection (GS). The prediction of disease resistance in GS has its own peculiarities: a) there is consensus ...
First report of Heterodera hordecalis, a cereal cyst nematode, on wheat in Algeria
(American Phytopathological Society, 2018)
In June 2016, six soil samples were collected from durum wheat (Triticum durum) fields of Guellal (36°2'7" N; 5°20'12" E), Hammam Sokhna (35°58’60" N; 5°48’0" E), Ain Arnat (36°10’60" N; 5°19’0" E), Seriana (35°41’37'' N; ...
Unlocking the genetic diversity of Creole wheats
(Nuture Publishing Group, 2016)
Climate change and slow yield gains pose a major threat to global wheat production. Underutilized genetic resources including landraces and wild relatives are key elements for developing high-yielding and climate-resilient ...
Genomic prediction models for grain yield of spring bread wheat in diverse agro-ecological zones
(Nature Publishing Group, 2016)
Genomic and pedigree predictions for grain yield and agronomic traits were carried out using high density molecular data on a set of 803 spring wheat lines that were evaluated in 5 sites characterized by several environmental ...
