The spring rapeseed variety Sheik is mentioned in publications dedicated to agronomic trials conducted in Sweden in the late 2000s. In the documentation of those years, it appears alongside the varieties Joplin, Larissa, Ritz, and Rollo.
The comparison of these varieties was based on an analysis of yield per hectare, as well as the consideration of specific characteristics such as lodging resistance, plant height, and maturity. Detailed data on grain quality indicators or precise scores for disease resistance are not provided in open sources.
