The line was obtained within the framework of breeding programs aimed at developing resistance to imidazolinone and sulfonylurea herbicides. It is used as genetic material for the development of hybrids possessing herbicide resistance via Clearfield and Clearfield Plus technologies, as well as resistance to broomrape.
This breeding line is characterized by compatibility with CL Plus technology. Information regarding the maturity group, plant height, lodging resistance, and product quality indicators is absent, as the material is an intermediate link in the breeding process and not a finished variety for commercial production.
