Illumina PE250 reads from pool of 86 Beta vulgaris subsp. maritima individuals from 38 US NPGS PI accessions
86 individuals from 38 PIs were selected to maximize genetic variation as predicted by 33 SSR loci. Immature leaf tissue was pooled, high molecular weight DNA extracted, fragmented to 450 bp prior to construction of a PCR-free sequencing library, then sequenced on a single lane of an Illumina NovaSeq 6000 instrument using an SP 500 flow cell and chemistry  to generate 250 bp paired end reads.
