Introduction
The use of sorghum to brew Baijiu, a traditional distilled liquor, has a history of thousands of years in China. These Baijiu-brewing sorghums are waxy and tannin-rich, exhibit distinct phynotypes from the reference genome inbred BTx623. However, little is known about the genome of these landraces. Here we present the complete telomere-to-telomere (T2T) genome assemblies of the representative Chinese Baijiu-brewing sorghum cultivar Hongyingzi (红缨子 for Maotai, the most famous Baijiu in China) from Chishui River basin and
Huandiaonuo (环雕糯, for Fen-flavor Baijiu) from Yangtze River basin, integrating PacBio HiFi, 100-kb ultra-long ONT (UL-ONT), and Hi-C sequencing technologies.
