The Hanna variety is used in scientific literature as material for studying the pathogens Verticillium longisporum and Leptosphaeria maculans. In publications, detailed agronomic characteristics, such as yield, plant height, or maturity group, are not provided, as the variety is not intended for mass commercial sowing.
The winter rapeseed hybrid Kharnas existing on the market is an independent product and is not related to the Hanna variety.
