Table 3.
Powdery mildew (Pm) infection rates of the sub-groups in the Nordic spring barley panel, consisting of 169 lines, based on data from the five different field locations during 2012–2014.
| No. of | Median | Average | ||
|---|---|---|---|---|
| Sub-groups | observations | Pm score∗ | rank | Z |
| K1 | 872 | 1.0a | 501.6 | -22.20 |
| K2 | 376 | 5.0b | 963.9 | 16.80 |
| Admixed | 104 | 5.0b | 1103.9 | 11.62 |
| Overall | 1353 | 676.5 |
∗Input data were the calculated mean from replicates of a certain line (and observation time if there was more than one scoring per season) for each location and year (N = 1353). Different lower case letters indicate statistically significant differences (p-value ≤ 0.05) using pair-wise Kruskal–Wallis comparisons. Average Rank = the average of the ranks for all observations within each sample. Z = value of how the average rank for each group compares to the average rank of all observations.
