Fig. 2. Association among 30 genotypes from a sugarcane germplasm collection as revealed by PCoA of genetic distances based on 18 TRAP primer combinations. Abbreviations: Mi, Miscanthus; Er, Erianthus; Cu, Cultivar; Ssp, Saccharum spontaneum; So, S. officinarum; Sr, S. robustum; Sb, S. barberi; Ssi, S. sinense; Hy, Hybrid; Dw, Dwarf. Numbers were used to uniquely identify a genotype (for example Ssp6) when there was more than one genotype representing a species or group.
