摘要： 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 of hexaploid wheat have been generated, but none is reported for SHW-derived cultivars. Here, we generated a chromosome-scale assembly for the SHW-derived cultivar 'Chuanmai 104' based on PacBio HiFi reads and chromosome conformation capture sequencing. The total assembly size was 14.81 Gb with a contig N50 length of 58.25 Mb. A BUSCO analysis yielded a completeness score of 99.30%. In total, repetitive elements comprised 81.36% of the genome and 122,554 high-confidence protein-coding gene models were predicted. In summary, the first chromosome-level assembly for a SHW-derived cultivar presents a promising outlook for the study and utilization of SHWs in wheat improvement, which is essential to meet the global food demand.
