Reading the results
- Compare varieties within the same crop, location and management system. Results from different trials are not a universal ranking.
- Source names are preserved. Similar spellings have not been assumed to be the same variety.
Source abbreviations are expanded above. Percent signs are retained where supplied; no missing unit is invented. CV describes variation; LSD is the source’s least significant difference.
