Figure 1.
A UPGMA dendrogram indicates genetic relationships of cultivated rice groups with different origins (see Table 1 and Table S1), using wild rice as an out-group.
The dendrogram was constructed based on the cluster analyses of Nei (1987) [20] unbiased genetic similarity of the rice groups.
Figure 2.
A GIS (geographical information system) map illustrating the genetic similarity of the Italian traditional rice verities (Italy-1) to those from Asia.
Rice varieties from China were further divided into subgroup represented by Provinces (see Table S1). The intensity (seven levels) of color-codes indicates the degree of relatedness as estimated by the Nei (1987) [20] unbiased genetic similarity. The legend at the right-down corner indicates the level of genetic similarity.
