Introduction
The Montana Statewide Spring Canola Variety Trial solicits regionally adapted canola varieties from commercial seed suppliers and provides agronomic performance data to Montana canola farmers. In 2025, performance of 21 canola hybrids was evaluated at four locations in the state (Moccasin, Sidney, Havre, Kalispell) under both irrigated (Sidney) and dryland conditions (all other locations).
Objectives
The objective of the 2025 Montana Statewide Spring Canola Variety Trial was to evaluate the agronomic performance of available canola hybrids and breeding lines submitted by commercial entities at testing locations across the state. The information obtained from these trials is intended to provide canola growers in Montana with unbiased information regarding which canola hybrids are best suited to their specific growing conditions.
