† Varieties that have any MS letter in common are not significantly different (Fisher’s Protected LSD, P<0.05). Mean separation was performed across all entries. Varieties within the “A group” were top performers across all entries and mean separation letters of these entries are highlighted in dark orange.
For ease of viewing, the table is broken into functional groups (brassicas, cereals, legumes). Mean values for top performers within each functional group are highlighted in light orange (50th – 75th percentile) and dark orange (> 75th percentile).
