We selected 12 representative G. barbadense accessions from around the world, including 7 primitively domesticated accessions from South America, 2 Sea Island landrace accessions from the Caribbean region, and 3 cultivated accessions. An average of 63.1 GB of high-fidelity (HiFi) reads were generated for the 12 accessions. These were initially assembled via HiFiasm into individual genomes ranging from 2.21 to 2.25GB in size (Table 1) and with contig N50 ranging from 55.0 Mb to 102.7 Mb (average = 70.4 Mb), longer than the previously published genome of G. barbadense.  These 98.40% (range 97.48% to 98.93%) assembled contigs were further anchored and ordered into 26 pseudo-chromosomes based on the 3-79 reference genome.  Assembly completeness was high for all assemblies, which contained more than 99.5% complete BUSCOs, and the LTR Assembly Index (LAI) scores ranged from 13.78 to 15.18 per genome, which is considered reference quality according to LAI scores (Table 1).

Markers
Marker alignments were performed by the CottonGen Team of Main Bioinformatics Lab at WSU. The alignment tool 'BLAT' was used to map marker sequences from CottonGen to the Gossypium barbadense GB249 v1.0 assembly. Markers required 90% identity over 97% of their length. For SSRs & RFLPs, gap size was restricted to 1000bp or less with less than 2 gaps. For dbSNPs and Indels gap size was restricted to 2bp with less than 2 gaps. The available files are in GFF3 format. Markers available in CottonGen are linked to JBrowse.
