Table 4.
Summary of the 68 meta QTL (mQTL) for grain yield and anthesis-silking interval detected across 18 maize populations
| Chromosome | Meta QTL name | K | Predicted meta QTL position (cM) | Meta QTL 95% genetic confidence interval (cM) | Initial number of QTL | Mean initial confidence interval (cM) | Mean LOD score of the initial QTL | Mean R2 for the initial QTL | Δ in the 95% confidence interval (cM) | 95% physical confidence interval (kb) | Physical distance (kb) | No. of candidate genes within the physical interval | No. of populations where the meta QTL was uncovered | |
