The hybrid is a medium-tall plant with a stem height of 170–180 cm. The vegetation period is from 110 to 116 days, which allows it to be classified in the mid-late maturity group, although under certain conditions it may be classified as mid-early.
The plant is characterized by uniformity, which contributes to homogeneous ripening and convenience during mechanized harvesting. It possesses genetic resistance to broomrape, while the spectrum of protection against various races (up to race G) may vary depending on test conditions.
