The Ph1031b line is specialized genetic material for breeding, not a commercial variety or hybrid for mass sowing. It is used in breeding programs to develop hybrid combinations adapted for various European regions.
Plants created based on this line are characterized by medium height, early flowering, and medium physiological maturity. Morphologically, the plants have an unbranched stem and broadly triangular or rounded leaves.
