Figure 3. Correlograms of spatial pattern for G. soja analyzed based on seven microsatellite primers. The r indicates correlation coefficient. U and L indicate the upper and lower limits by 95% confidence interval for the null hypothesis of no spatial structure. Distance classes corresponding to three different levels [5 m, 10 m, 15 m, 20 m, 25 m, 30 m, 35 m, 40 m, 45 m, 50 m, and 55 m (intra-pop)], [0.1 km, 0.4 km, 2.0 km, 10 km, and 20 km (inter-pop/intra-regions)], and [400 km, 1000 km, 1200 km (inter-region)] are shown along logarithmic x-axis.
