Overall morphological variations observed in tomato accessions.
Pie diagram represents percent contribution of each character towards total variability to reference cultivar, Arka Vikas.

Clustering of the tomato accessions on the basis of 55 fruit attributes.
Agglomerative hierarchical clustering by unweighted pair-group average method was used for clustering. The accessions were grouped into 9 classes (C1-C9). Each class is represented by a different color in the dendrogram. The dotted line on dendrogram represents the position of truncation for defining the 9 classes. The heat map on left side of dendrogram shows the relative values of five selected fruit attributes.

Clustering of accessions based on SNP polymorphism.
The tree was made using the Neighbor-Joining method in MEGA4 taking together the sequences of all the genes. Substitutions are represented by branch lengths and the bootstrap value is indicated as numbers above the branches (10000 replicates).
