Abstract
As the water deficit in the area of Poland is predicted to be increasing, the role of drought as the main stress factor will grow and will limit yields. Analyses done on the basis of the recommendation trials showed a lack of registered varieties tolerant to drought stress. Therefore, there is a need for more emphasis on selection of breeding material suited for conditions with frequent water deficits. The presented results show that in the system of pre- and post-registration trials there are locations characterized by a relative high stress index and therefore suitable for efficient selection of new varieties.
