The hybrid belongs to the NuSun type, which means mid-oleic oil quality. The CLDM designation indicates technological resistance to Clearfield system herbicides and genetic resistance to downy mildew.
Plants reach a height of about 195–200 cm. Under field conditions, the hybrid may show susceptibility to certain races of sunflower rust and broomrape; herbicide treatment is applied to control the latter.
