‘Soft white spring wheat ( Triticum aestivum L.) is an important wheat class for domestic and international markets and is widely grown in the U.S. Pacific Northwest (PNW). The objective of this study was to develop a soft white spring (SWS) wheat cultivar with high grain yield, desirable end‐use quality, and resistance to Fusarium head blight [FHB; caused by Fusarium graminearum Schwabe; telomorph Gibberella zeae (Schwein.) Petch], an emerging disease of spring wheat in southern Idaho and some areas in the PNW. ‘UI Stone’ (Reg. No. CV‐1088, PI 660550) SWS wheat was developed by the Idaho Agricultural Experiment Station using a modified backcross breeding procedure. UI Stone was derived from a backcross ‘Pomerelle’ *2/‘Tui’ made in 1994 in Aberdeen, ID and tested under experimental numbers A94368‐B‐7 and IDO599. UI Stone was released for its superior grain yield under both unirrigated and irrigated production conditions in southern Idaho and the PNW, its excellent end‐use quality, and its resistance to FHB. The heading date of UI Stone is similar to that of the early‐maturity cultivar ‘Nick’ but later than that of ‘UI Pettit’ (PI 620631) and earlier than that of ‘Alturas’ (PI 620631), ‘Louise’ (PI 634865), and ‘Alpowa’ (PI 566596). UI Stone has potential to replace Alturas and UI Pettit in southern Idaho and to replace Alpowa, Louise, and Nick in the PNW.
