Neighbour joining analysis of representative samples of tomato species using 4072 SNPs. Solanum pennellii accession LA0716 was used as outgroup. Numbers at the nodes are bootstrap values for 1000 re-samplings. Numbers in brackets are the number of non-calls per genotype. Markers that were for more than 98% monomorphic, or had more than 25% heterozygous scores or more than 20% no-calls in the commercial hybrids or more than 50% in the wild relatives were removed from the dataset leaving a total of 4072 markers.
