Genotyping-by-sequencing (GBS) is a high-throughput genotyping approach that starting to be used in several crop species, including bread wheat. Anchoring GBS tags on chromosomes an important step towards utilizing them for wheat genetic improvement. Here we use linkage mapping construct consensus map containing 28644 markers. Three RIL populations, PBW343 × Kingbird, Kenya Swara and Muu, which share common parent, were minimize the impact of potential structural genomic variation...
Abstract Undomesticated wild species, crop relatives, and landraces represent sources of variation for wheat improvement to address challenges from climate change the growing human population. Here, we study 56,342 domesticated hexaploid, 18,946 tetraploid 3,903 relatives in a massive-scale genotyping diversity analysis. Using DArTseq TM technology, identify more than 300,000 high-quality SNPs SilicoDArT markers align them three reference maps: IWGSC RefSeq v1.0 genome assembly, durum...
Abstract This study examines genomic prediction within 8416 Mexican landrace accessions and 2403 Iranian stored in gene banks. The collections were evaluated separate field trials, including an optimum environment for several traits, two environments (drought, D heat, H) the highly heritable days to heading (DTH), maturity (DTM). Analyses accounting not population structure performed. Genomic models include genotype × interaction (G E). Two alternative strategies studied: (1) random...
Abstract To accelerate genetic gains in breeding, physiological trait (PT) characterization of candidate parents can help make more strategic crosses, increasing the probability accumulating favorable alleles compared to crossing relatively uncharacterized lines. In this study, crosses were designed complement “source” with “sink” traits, where at least one parent was selected for expression biomass and/or radiation use efficiency—source—and other sink-related traits like harvest-index,...
Identifying and mobilizing useful genetic variation from germplasm banks to breeding programs is an important strategy for sustaining crop improvement. The molecular diversity of 1,423 spring bread wheat accessions representing major global production environments was investigated using high quality genotyping-by-sequencing (GBS) loci, gene-based markers various adaptive traits. Mean index (DI) estimates revealed synthetic hexaploids be genetically more diverse (DI= 0.284) than elites (DI =...
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...
Abstract The value of exotic wheat genetic resources for accelerating grain yield gains is largely unproven and unrealized. We used next-generation sequencing, together with multi-environment phenotyping, to study the contribution genomes 984 three-way-cross-derived (exotic/elite1//elite2) pre-breeding lines (PBLs). Genomic characterization these haplotype map-based SNP marker approaches revealed specific imprints 16.1 25.1%, which compares theoretical expectation 25%. A rare favorable (GT)...
Abstract Climate change and slow yield gains pose a major threat to global wheat production. Underutilized genetic resources including landraces wild relatives are key elements for developing high-yielding climate-resilient varieties. Landraces introduced into Mexico from Europe, also known as Creole wheats, adapted wide range of climatic regimes represent unique resource. Eight thousand four hundred sixteen representing all dimensions were characterized through genotyping-by-sequencing...
Abstract Synthetic hexaploid (SH) wheat (AABBD’D’) is developed by artificially generating a fertile hybrid between tetraploid durum ( Triticum turgidum , AABB) and diploid wild goat grass Aegilops tauschii D’D’). Over three decades, the International Maize Wheat Improvement Center (CIMMYT) has utilized SH to bridge gene transfer from Ae . bread wheat. This unique example of success utilizing relatives in mainstream breeding at large scale worldwide. Our study aimed determine genetic...
Abstract Crop landraces have unique local agroecological and societal functions offer important genetic resources for plant breeding. Recognition of the value landrace diversity concern about its erosion on farms led to sustained efforts establish ex situ collections worldwide. The degree which these succeeded in conserving has not been comprehensively assessed. Here we modelled potential distributions eco-geographically distinguishable groups 25 cereal, pulse starchy root/tuber/fruit crops...
Cereal production is strongly influenced by flowering date. Wheat ( Triticum aestivum L.) models simulate days to flower assuming that development modified vernalization and photoperiodism. Cultivar differences are parameterized requirement, photoperiod sensitivity, earliness per se. The parameters usually estimated comparing simulations with field observations but appear estimable from genetic information. For wheat, the Vrn Ppd loci, which affect photoperiodism, were logical candidates for...
ABSTRACT The Global Wheat Program of the International Maize and Improvement Center (CIMMYT) develops distributes improved germplasm targeted toward various wheat growing regions developing world. objective our study was to quantify genetic yield gains in CIMMYT's spring bread ( Triticum aestivum L.) Elite Spring Yield Trial (ESWYT) distributed over past 15 yr (1995–2009) as determined by performance entries across 919 environments 69 countries. To determine annual gains, differences mean...
Abstract Development of winter wheat ( Triticum aestivum ) synthetics started at CIMMYT-Mexico in 2004, when durum turgidum germplasm from Ukraine and Romania was crossed with Aegilops tauschii accessions the Caspian Sea region. Chromosomes were doubled after pollination embryo rescue, but chromosome number cytological validation not performed. F 2 populations grown Mexico shipped to Turkey 2008. During 2009–2015, these subjected rigorous pedigree selection under dry, cold, disease-affected...
The international collections of plant genetic resources for food and agriculture (PGRFA) hosted by 11 CGIAR Centers are important components the United Nations Food Agriculture Organization's global system conservation use PGRFA. They also play an supportive role in realizing Target 2.5 Sustainable Development Goals. This paper analyzes genebanks' trends acquiring distributing PGRFA over last 35 years, with a particular focus on decade. highlights number factors influencing Centers'...
