Trials on the economic value (VCU) of this variety in Lithuania was carried out in 2020/2021, 2021/2022 and 2022/2023.

Trials were carried out in various plant variety testing departments:

• Plunges plant variety testing department (Plunges AVTS)

• Kaunas Plant variety testing Department (Kaunas AVTS)

• Pasvalio plant variety testing department (Pasvalio AVTS)

• Utena plant variety testing department (Utena AVTS)
