Table 5.
Test of dominance and epistatic effects among the SNPs selected as cofactors in the GWAS of the whole population for flowering and ripening periods.
| Trait | Effects | d.f. | F-test | p-value | PVE (%) |
|---|---|---|---|---|---|
| Flowering period | Additive | 2 | 79.8 | 4.3E-33 | 9.1 |
| Dominance | 2 | 5.9 | 2.7E-03 | 0.7 | |
| Epistatic | 4 | 9.0 | 3.7E-07 | 2.0 | |
| Ripening period | Additive | 6 | 106.6 | 3.4E-106 | 17.4 |
| Dominance | 6 | 1.1 | 3.6E-01 | 0.2 | |
| Dominance of SNP.3-4 | 1 | 4.8 | 2.8E-02 | 0.1 | |
| Dominance of SNP.3-6 | 1 | 4.5 | 3.3E-02 | 0.1 | |
| Epistatic | 41a | 1.2 | 2.3E-01 | 1.3 |

Some combinations of SNP genotypes did not exist in the whole population, which reduced the df for all interactions between 6 SNPs.
