Chromosome-Scale Assembly of Wheat Cultivar Sumai 3, a Major Germplasm Source for Fusarium Head Blight Resistance
Year: 2026

Fusarium head blight (FHB) is a devastating disease that severely impacts global wheat production. Sumai 3, a wheat cultivar widely used in breeding programs for its strong FHB resistance, has not been fully resolved at the chromosome level. Here, we present a high-quality chromosome-scale assembly of Sumai 3 using PacBio HiFi reads, and chromosome conformation capture sequencing. The 14.6 Gb assembly consists of 832 contigs, with the longest contig being 245.2 Mb and a contig N50 of 41.90 Mb, w
