Fig. 2From: Microsatellite loci for Urochloa decumbens (Stapf) R.D. Webster and cross-amplification in other Urochloa speciesUnrooted neighbor-joining tree based on Jaccard’s coefficient for the 34 genotypes of the Urochloa species. The genotypes were named according to the annotated numbers listed in Table 1.
