Table 1.
Median rank and estimated relative effects (pi) of the canola hybrids “46S53RR”, “1950RR”, “Invigor 5440”, and the cultivar “Westar” on blackleg severity. Trials were conducted under field conditions near Edmonton (Crop Diversification Centre North; CDCN) and Namao, Alberta in 2013, 2014 and 2015.
| Sites/Years | Canola Cultivar/Hybrid | Median Disease Rating | Mean Rank (Ri) | Estimated Relative Effect (pi) | SE | Confidence Interval (95%) for the Estimated Relative Effect | |
|---|---|---|---|---|---|---|---|
| Lower | Upper | ||||||
| CDCN and Namao, 2013 and 2014 | 46S53RR | 1.0 | 25.73 | 0.35041 | 0.028 | 0.30389 | 0.40557 |
| 1950RR | 1.0 | 33.90 | 0.46383 | 0.042 | 0.39920 | 0.53134 | |
| Westar | 2.0 | 49.88 | 0.68576 | 0.049 | 0.60437 | 0.74412 | |
| CDCN and Namao, 2015 | Invigor 5440 | 1.0 | 5.13 | 0.28906 | 0.066 | 0.25906 | 0.39010 |
| Westar | 2.0 | 11.88 | 0.71094 | 0.058 | 0.60990 | 0.74094 | |
The pi estimates were determined by SE(Ri)/N, in which SE(Ri) is the standard error of the mean rank for the ith cultivar as determined in the Mixed procedure of SAS with the lsmeans option. A cultivar/hybrid with a pi value outside the confidence interval of any other cultivar/hybrid is significantly different from the other cultivar/hybrid (p ≤ 0.05).
