Interpretive Summary: Stripe rust resistance is an essential trait for spring wheat cultivars produced in the Pacific Northwest region of the United States. The objective of this research was to develop an adapted spring wheat cultivar with high levels of resistance to stripe rust. ‘Whit’ (PI 653841) soft white spring wheat was developed and released in July 2008 by the Agricultural Research Center of Washington State University. Whit is an intermediate-height semidwarf cultivar adapted to the intermediate to high rainfall (>380 mm of average annual precipitation), nonirrigated wheat production regions of Washington and Idaho. Whit is resistant to Hessian fly, has high-temperature, adult-plant resistance to local races of stripe rust, is intermediate in height, is early maturing, and has high grain yield potential. Whit is a partial waxy variety with end-use quality properties similar or superior to ‘Louise’, ‘Alpowa’, and ‘Alturas’.

Technical Abstract: Stripe rust (Puccinia striiformis Westend f. sp. tritici) resistance is an essential trait for spring wheat cultivars produced in the Pacific Northwest region of the United States. The objective of this research was to develop an adapted spring wheat cultivar with high levels of resistance to stripe rust. ‘Whit’ (Reg. No. CV-1034, PI 653841) soft white spring wheat (Triticum aestivum L.) was developed and released in July 2008 by the Agricultural Research Center of Washington State University. Whit was tested under the experimental designations SW2K067, S0300100U, and WA008008, which were assigned through progressive generations of advancement. Whit is an intermediate-height semidwarf cultivar adapted to the intermediate to high rainfall (>380 mm of average annual precipitation), nonirrigated wheat production regions of Washington and Idaho. Whit is resistant to Hessian fly [Mayetiola destructor (Say)], has high-temperature, adult-plant resistance to local races of stripe rust, is intermediate in height, is early maturing, and has high grain yield potential. Whit is a partial waxy variety with end-use quality properties similar or superior to ‘Louise’, ‘Alpowa’, and ‘Alturas’.
