Wheat is an important staple that acts as a primary source of dietary energy, protein, and essential micronutrients such iron (Fe) zinc (Zn) for the world's population. Approximately two billion people suffer from micronutrient deficiency, thus breeders have crossed high Zn progenitors synthetic hexaploid wheat, T. dicoccum, spelta, landraces to generate wheat varieties with competitive yield enhanced grain are being adopted by farmers in South Asia. Here we report genome-wide association...
Breeding wheat with enhanced levels of grain zinc (Zn) and iron (Fe) is a cost-effective, sustainable solution to malnutrition problems. Modern varieties have limited variation in Zn Fe, but large-scale screening has identified high Fe wild relatives progenitors cultivated wheat. The most promising sources are einkorn (Triticum monococcum), emmer (T. dicoccoides), diploid hexaploid (such as Aegilops tauschii), T. spelta, polonicum, landraces aestivum. This study evaluate the effects...
Wheat ( Triticum aestivum L.) is a major staple food crop grown worldwide on >220 million ha. Climate change regarded to have severe effect wheat yields, and unpredictable drought stress one of the most important factors. Breeding can significantly contribute mitigation climate effects production by developing drought‐tolerant germplasm. The objective our study was determine annual genetic gain for grain yield (GY) internationally distributed Semi‐Arid Yield Trials, during 2002–2003...
We calculated the annual genetic gains for grain yield (GY) of wheat ( Triticum aestivum L.) achieved over 8 yr international Elite Spring Wheat Yield Trials (ESWYT), from 2006–2007 (27th ESWYT) to 2014–2015 (34th ESWYT). In total, 426 locations were classified within three main megaenvironments (MEs): ME1 (optimally irrigated environments), ME4 (drought‐stressed and ME5 (heat‐stressed environments). By fitting a factor analytical structure modeling genotype × environment (G E) interaction,...
Genomic selection and high-throughput phenotyping (HTP) are promising tools to accelerate breeding gains for high-yielding climate-resilient wheat varieties. Hence, our objective was evaluate them predicting grain yield (GY) in drought-stressed (DS) late-sown heat-stressed (HS) environments of the International maize improvement center's elite trial nurseries. We observed that average genomic prediction accuracies using fivefold cross-validations were 0.50 0.51 DS HS environments,...
More than 50% of undernourished children live in Asia and more 25% Africa. Coupled with an inadequate food supply, mineral deficiencies are widespread these populations; particularly zinc (Zn) iron (Fe) that lead to retarded growth, adverse effects on both the immune system individual's cognitive abilities. Biofortification is one solution aimed at reducing incidence deficiencies. To efficiently breed a biofortified wheat variety, it important generate knowledge genomic regions associated...
Rust diseases continuously threaten global wheat production: stem rust, leaf rust and yellow caused by Puccinia graminis f. sp. tritici, triticina striiformis f.sp. respectively. Recent studies indicated that losses from all three rusts average at least 15.04 million tons per year, which is equivalent to an annual loss of around US $2.9 billion year. The major focus Mexican worldwide breeding programs the release resistant cultivars, as this considered best option for controlling diseases....
Abstract Malnutrition because of the deficiency minerals such as iron (Fe) and zinc (Zn) afflicts over 2 billion people worldwide. Wheat is a major staple crop, providing 20% dietary energy protein consumption Breeding wheat with elevated levels grain Zn Fe concentrations ( GZn GFe ) represents significant opportunity to increase intake these micronutrients for resource poor who depend on it source energy. Synthetic hexaploid wheats SHWs have large genetic variation , which can be exploited...
Genomic selection (GS) has been promising for increasing genetic gains in several species. Therefore, we evaluated the potential integration of GS grain yield (GY) bread wheat ( Triticum aestivum L.) CIMMYT's elite trial nurseries. We observed that genomic prediction accuracies within nurseries (0.44 and 0.35) were substantially higher than across‐nursery (0.15 0.05) GY bed flat planting systems, respectively. The from using only a subset 251 genotyping‐by‐sequencing markers comparable to...
Grain yield progress over 50 years of spring wheat breeding at the International Maize and Wheat Improvement Center (CIMMYT) was determined in field trials conducted during five crop seasons (2013–2017) Norman E. Borlaug research station near Ciudad Obregon, Mexico. The included 30 varieties (24 bread 6 durum wheat) released between 1965–2014 were sown under managed optimum, drought, heat stress conditions. optimum irrigated environment had 3 management systems, flat sowing with weekly drip...
In this study, we defined the target population of environments (TPE) for wheat breeding in India, largest producer South Asia, and estimated correlated response to selection prediction ability five (SEs) Mexico. We also grain yield (GY) gains each TPE. Our analysis used meteorological, soil, GY data from international Elite Spring Wheat Yield Trials (ESWYT) distributed by International Maize Improvement Center (CIMMYT) 2001 2016. identified three TPEs: TPE 1, optimally irrigated...
Wheat dough characteristics and end-use quality are strongly influenced by the amount specific composition of glutenins, major components gluten. Such proteins divided into high-molecular-weight encoded Glu-A1, Glu-B1 Glu-D1 loci; low-molecular-weight Glu-A3, Glu-B3 Glu-D3 loci. Allelic variation at each these loci has been associated with changes in wheat functionality. However, most studies conducted so far included a relatively limited number genotypes. Also for this reason, it is still...
Aphid salivary effectors play important roles in modulating plant defense responses. The grain aphid Sitobion miscanthi is one of the most economically cereal aphids worldwide. However, little information available on identification and functional analysis S. miscanthi. In this study, a candidate effector Sm9723 was identified, which specifically expressed glands highly induced during feeding phase. Transient overexpression Nicotiana benthamiana suppressed BAX INF1-induced cell death....
The effects of climate change together with the projected future demand represents a huge challenge for wheat production systems worldwide. Wheat breeding can contribute to global food security through creation genotypes exhibiting stress tolerance and higher yield potential. objectives our study were (
Abstract Linking high-throughput environmental data (enviromics) to genomic prediction (GP) is a cost-effective strategy for increasing selection intensity under genotype-by-environment interactions (G × E). This study developed data-driven approach based on Environment–Phenotype Association (EPA) aimed at recycling important G E information from historical breeding data. EPA was in two applications: (1) scanning secondary source of genetic variation, weighted the shared reaction-norms...
Abstract Genomic selection (GS) in wheat breeding programs is of great interest for predicting the genotypic values individuals, where both additive and nonadditive effects determine final value lines. While several simulation studies have shown efficiency rapid-cycling GS strategies parental or population improvement, their practical implementations are still lacking other crops. In this study, we demonstrate potential rapid-cycle recurrent (RCRGS) to increase genetic gain grain yield (GY)...
Genomic selection (GS) is transforming plant and animal breeding, but its practical implementation for complex traits multi-environmental trials remains challenging. To address this issue, study investigates the integration of environmental information with genotypic in GS. The proposes use two feature methods (Pearson's correlation Boruta) information. Results indicate that simple incorporation covariates may increase or decrease prediction accuracy depending on case. However, optimal using...
