Sorghum (Sorghum bicolor (L.) Moench) is a world cereal crop used in China for producing Baijiu, a distilled spirit. We report a telomere-to-telomere genome assembly of the Baijiu cultivar Hongyingzi, HYZ-T2T, using ultralong reads. The 10 chromosome pairs contained 33,462 genes, of which 93% were functionally annotated. The 20 telomeres and 10 centromeric regions on the HYZ-T2T chromosomes were predicted and two consecutive large inversions on chromosome 2 were characterized. A 65-gene reconstruction of the metabolic pathway of tannins, the flavor substances in Baijiu, was performed and may advance the breeding of sorghum cultivars for Baijiu production.
