In recent years, wheat yield per hectare appears to have reached a plateau, leading concerns for future food security with an increasing world population. Since its invention, synthetic hexaploid (SHW) has been shown be effective genetic resource transferring agronomically important genes from wild relatives common wheat. It provides new sources potential, drought tolerance, disease resistance, and nutrient-use efficiency when bred conventionally modern varieties. SHW is becoming more...
Synthetic hexaploid wheats (SHWs) are effective genetic resources for transferring agronomically important genes from wild relatives to common wheat (Triticum aestivum L.). Dozens of reference-quality pseudomolecule assemblies have been generated, but none is reported SHW-derived cultivars. Here, we generated a chromosome-scale assembly the cultivar 'Chuanmai 104' based on PacBio HiFi reads and chromosome conformation capture sequencing. The total size was 14.81 Gb with contig N50 length...
<title>Abstract</title> Stripe rust is prevalent in the wheat-growing region of southwestern China. Frequent changes stripe pathogen virulence this lead to a rapid loss disease resistance among wheat varieties. However, Chinese landrace Yizhanghongkemai (YZHK) has exhibited adult-plant for more than one decade nursery To elucidate underlying genetic basis, quantitative trait loci (QTLs) YZHK were analyzed using an inclusive composite interval mapping method. Six QTLs detected on chromosomes...
ABSTRACT Synthetic hexaploid wheat (SHW) is a valuable source of genetic diversity for germplasm enrichment in breeding. In China, SHW‐derived material has shown significant yield increases. A 3‐yr field experiment at Guanghan and Jiangyou the Sichuan Basin China was conducted to characterize potential three cultivars (SDCs) with five local elite nonsynthetic‐derived as checks (NSCs). On average, SDCs showed an 11.5% or 951 kg ha −1 increase compared NSCs. This gain mainly attributed...
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most devastating fungal diseases wheat worldwide. It essential to discover more sources stripe rust resistance genes for breeding programs. Specific locus amplified fragment sequencing (SLAF-seq) a powerful tool construction high-density genetic maps. In this study, set 200 recombinant inbred lines (RILs) derived from cross between cultivars Chuanmai 42 (CH42) and 55 (CH55) was used construct map identify...
The objective of this research was to characterize the high level resistance stripe that has been observed in released wheat cultivar, Chuanmai45. A combination classic genetic analysis, molecular and cytogenetic methods were used an F2 population derived from Chuanmai45 susceptible Chuanmai42. Inheritance shown be conferred by two genes Fluorescence situ hybridization (FISH) along with segregation studies show one gene located on a 1RS.1BL translocation. Molecular markers employed other...
Continuous improvement of potential yield is one the most important goals wheat breeding. The introduction synthetic hexaploid (SHW) germplasm has broken bottleneck in yield, taking breeding China’s Sichuan Basin to a new level. However, systematic research on physiological basis high-yielding, SHW-derived cultivars lagged behind. In present study, three SHW-derived, high-yielding and typical, non-synthetic widely used production were chosen for 5-year study. Post-anthesis canopy structure,...
Genetic diversity and relationships of wild goat grass (Aegilops tauschii Cosson) from Iran Xinjiang, west China, as well its weedy type the Yellow River region Shaanxi Henan provinces in China were analyzed by simple sequence repeat (SSR) fingerprints. A high level genetic Aegilops accessions was observed, richness followed Shaanxi, Henan, Xinjiang. The showed a close relationship with different regions Iran. results indicated that found most likely introduced Iran—the center tauschii....
Glutamine synthetase TaGSr-4B is a candidate gene for QTL of thousand grain weight on 4B, and the marker ready wheat breeding. A (TGW) in was previously mapped chromosome 4B DH population Westonia × Kauz. For identifying genes QTL, 90 K SNP array used to saturate existing linkage map, four field trials plus one glasshouse experiment over five locations were conducted refine QTL. Three nitrogen levels applied two those trials, resulting TGW phenotype data set from nine environments. robust...
Abstract Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a devastating disease that can cause severe yield losses. Identification and utilization of rust resistance genes are essential for effective breeding against the disease. Wild emmer accession TZ-2, originally collected from Mount Hermon, Israel, confers near-immunity several prevailing Pst races in China. A set 200 F6:7 recombinant inbred lines (RILs) derived cross between susceptible durum wheat cultivar...
Common wheat is one of the most important crops in China, which largest producer world. A set 230 cultivars was used to identify yield-related loci by association mapping. This tested for seven traits, viz. plant height (PH), spike length (SL), spikelet number per (SNPS), kernel (KNPS), thousand-kernel weight (TKW), (KWPS), and sterile (SSN) four environments. total 106 simple sequence repeat (SSR) markers distributed on all 21 chromosomes were screen set. Twenty-one 19 them associated with...
Entomopathogenic nematodes (EPN) are potent microbial biocontrol agents applied commercially against various economically important insect pests. The efficacy of EPN in the field may be partially reduced when compared to chemical insecticides due its sensitivity environmental stressors like temperature, desiccation, and UV light. Thus, researchers have developed methods enhance effectiveness EPN, such as screening or breeding stress-resistant strains creating adjuvants for protection field....
