From: Mining sequence variations in representative polyploid sugarcane germplasm accessions
A divergent time tree of the 14 accessions and sorghum generated by maximum likelihood method. The unit for the number at the branch of the tree indicates divergence in million years. Abbreviation in bracket: S. r = S. robustum; S. o = S. officinarum; S. h = Saccharum hybrid; S. b = S. barberi; S. si = S. sinense; S. sp. = S. spontaneum; E. r = E. rufipilu; E. p = Erianthus procerum, and un = unknown
