Statewide Canola Variety Evaluation 2015
To evaluate canola varieties for agronomic performance in environments and cropping systems representative of northwestern Montana.
Significant differences were observed in plant density, flowering date, plant height, yield, percent oil, and test weight. Plants density averaged 15.5 plants/ft2 and ranged from 9.8 plants/ft2 for Cara to 20.4 plants/ft2 for InVigor L130. Flowering date averaged 169 days (June 18) and spanned a 5 day period that ranged from 166 to 171 days. Plant height averaged 47.7 inches and ranged from 41.8 inches for Arriba to 53.3 inches for InVigor 5440. Lodging averaged 11.6% however, no significant difference was observed among entries. Shatter was 0.0% for all varieties. Yields averaged 61.3 bu/A and ranged from 43.2 bu/A for Cara to 72.9 bu/A for InVigor 5440. Oil content averaged 50.4%, ranging from 46.8% for InVigor L130 to 54.8% for 6074RR and C1516. Test weights averaged 51.0 lb/bu and ranged from 48.5 lb/bu for HyClass 955 to 57.4 lb/bu for C1516.
InVigor 5440 was the highest yielding variety and had an oil content of 49.5%. Based on the LSD value for yield at 12.4, 11 varieties were statistically equivalent to InVigor 5440.
