Specimen notes
Supplementary remarks:
genome size identical to Sorghum ×sudan BMR [Seedforce] (= Sorghum bicolor subsp. drummondii or sometimes called S. sudanese). This makes it highly unlikely that the sample is either S. halpense or a hybrid of S. halpense with some other species. S. halpense has double the chromosome number of S. bicolor (40 vs 20), and the genome size in picograms is also approximately double (1.67 to 3.27). As the standard we used is known from the literature to have 20 chromosomes, and the divergence between the samples was approximately 2.1%, which is within the error of the instrument, we can likely rule out S. halpense as a possible parent.
