KWS Sterling

KWS Sterling (W152), currently in RL trials, is a new provisional Group 2 hard milling wheat, with good breadmaking quality, HFN and specific weight. Yielding some 3% above Einstein and Cordiale and at a similar level to Panorama, it has short and very stiff straw, with a good set of disease resistance scores. KWS second wheat trials show KWS Sterling to be especially suited to this rotational position, with yields at least as high as Duxford.
