Fig. 2. Pair-wise comparison of average P.I.C. values of SSR markers evaluated on 13 cultivars of Oryza sativa vs. 256 diverse O. sativa cultivars (Y. Xu, personal communication) (Comparison 1), and 5 vs. 51 O. sativa spp. Japonica cultivars (Ji et al., 1998) (Comparison 2). Differences between P.I.C. values for individual markers for each comparison are shown graphically.
