Other claims from this paper (10)
- Method / resource Twenty-five SSR markers generated 224 polymorphic bands in maize populations.
- Method / resource Three AFLP primer combinations generated 188 bands in maize populations.
- Method / resource Of the AFLP bands, 79.2% were polymorphic.
- Method / resource The average polymorphism content (PIC) was higher for SSRs than for AFLPs (0.79 versus 0.28).
- Method / resource Genetic similarity values estimated for AFLPs were higher than those for SSRs.
- Method / resource The Pearson correlation between SSR and AFLP genetic similarities was low (0.149), indicating poor agreement between the marker systems.
- Method / resource The ranking of agro-ecological groups by mean GS values was congruent for both marker systems.
- Method / resource The Pearson correlation coefficient calculated from the mean GS values was 0.853.
- Method / resource Cluster analysis agreed much better with agro-ecological expectations when using AFLP analysis than SSR markers.
- Method / resource When using a DNA-pooling strategy, AFLPs are more reliable than SSRs for assessing genetic diversity of maize populations.
