Objective:
To evaluate the agronomic performance of currently available or soon to be released varieties and breeding lines of canola in the many diverse climates of Montana
Personnel:
Clint Beiermann, Jessica Pavelka
Summary:
Twenty-six varieties of canola were planted on April 29th, 2022 and managed under rainfed conditions until harvest on September 8th, 2022 (Table 1). This trial was one of five that were conducted across the state on Montana (Figure 1). Eight seed companies contributed seed for the twenty-six varieties, with eight different herbicide resistance traits used for the varieties.
The average yield was 65.5 bu/A with the lowest at 53.6 bu/A for CP9919RR and the highest yield being 74.2 bu/A from InVigor L345PC. The highest oil content came from CP930RR at 50.4% and the lowest from NCC101S at 44.4%. The average oil content was 48.1%. The average height across all varieties was 47.0”, with the tallest being BY 6217TF at 58.7” and the shortest, CP9919RR, at 31.7”. The earliest flowering date was shared by NCC101S and CP9919RR at 175 julian, and the latest was BY 6217TF at 181 julian. The average julian flowering date was 178.
