The object is an inbred line developed for research purposes, not a commercial hybrid. It is used as breeding material for conducting genetic research and developing new hybrid forms.
A characteristic feature of this line is its resistance to imidazolinone herbicides, which is reflected in the abbreviation of its name. It is also used in scientific experiments for studying plant responses to moisture deficit and for phenotyping.
