Table 1.
Pair-wise comparisons for differences in genotype frequencies between Phaeosphaeria nodorum collections made from different hosts in 2004 based on a contingency χ2 test.
| Levis | Runal | Mixture | Tamaro | Tirone | |
|---|---|---|---|---|---|
| Levis | --- | 10.24 (7) | 7.43 (6) | 14.06 (8) | 9.07 (8) |
| Runal | 12.66 (7) | --- | 5.53 (7) | 7.38 (8) | 8.41 (8) |
| Mixture | 5.42 (7) | 9.29 (7) | --- | 6.69 (8) | 11.37 (8) |
| Tamaro | 7.32 (7) | 13.39 (7) | 4.86 (7) | --- | 14.98 (8) |
| Tirone | 7.68 (8) | 20.51 (7)** | 14.59 (8) | 16.33 (8)* | --- |
Above the diagonal are comparisons between populations sampled in early 2004 (2004A) and below the diagonal are comparisons between populations made in late 2004 (2004B). Values in bold font are significant after Bonferroni correction at a global alpha of 0.05 (p-value of 0.05/10 = 0.005) and values in parenthesis are degrees of freedom.
* Significant at p = 0.05 before Bonferroni correction
** Significant at p = 0.01 before Bonferroni correction
