The hybrid possesses genetic resistance to post-emergence imidazolinone herbicides, which allows for weed control without the risk of phytotoxicity to the crop. High productivity is noted when a balanced mineral nutrition is provided, which positively affects the thousand kernel weight and test weight.
The plant is resistant to downy mildew and exhibits tolerance to Phomopsis and white rot.
