Phylogenetic trees of 339 sorghum lines in the BAP. Phylogenetic trees were conducted using SNPs (A) and SVs (B) as characters. Sorghum variety type and photoperiod sensitivity were marked as different colors and shapes: cellulosic (green line), grain (yellow line), sweet (red line), photoperiod insensitive (blue solid circle), photoperiod sensitive (blue solid triangle), selected representative cellulosic accessions (red solid pentagram), and selected representative sweet accessions (red hollow pentagram). The maximum likelihood phylogenetic tree based on the SV data set shows a clearer classification of phylogeny, sorghum variety type, and photoperiod sensitivity than the maximum likelihood phylogenetic tree based on SNPs, with selected cellulosic and sweet sorghums being almost monophyletic based on SV data.
