Resistance to strawbreaker foot rot (caused by Oculimacula yallundae Crous & W. Gams and O. acuformis Crous & W. Gams), stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici iformisEriks.), and Cephalosporium stripe (caused by Cephalosporium gramineum Nisikado and Ikata) are important traits for winter wheat ( Triticum aestivum L.) cultivars produced in the Pacific Northwest region of the United States. The objective of this research was to develop an adapted winter wheat cultivar with effective resistance to these diseases. ‘Puma’ (Reg. No. CV-1097, PI 670038) soft white winter wheat ( Triticum aestivum L.) was developed and released in August 2013 by the Agricultural Research Center of Washington State University. Puma was tested under the experimental designations 5J030731, 5J030731–2, and WA008134, which were assigned through progressive generations of advancement. Puma is a semidwarf cultivar adapted to intermediate to high rainfall (>400 mm of average annual precipitation), unirrigated wheat production regions of Washington. Puma is resistant to strawbreaker foot rot, has high-temperature, adult-plant resistance to the stripe rust pathogen, is tolerant to Cephalosporium stripe, is intermediate in height, has midseason maturity, and has a high test weight and grain yield potential. Puma has end-use quality properties similar or superior to those of ‘Stephens’, ‘Brundage 96’, and ‘Xerpha’.

Many of the current soft white winter (SWW) wheat (Triticum aestivum L.) cultivars produced in Washington are adapted to specifi c environments. The objective of this research was to develop a high yielding, disease resistant SWW cultivar with competitive yield potential for all Washington winter wheat production environments. 'Xerpha' (Reg. No. CV-1045, PI 645605) SWW wheat was developed by the Agricultural Research Center of Washington State University (WSU) and released in 2008. It was selected from an 'Eltan'/'Estica' cross made in 1999 and advanced to the F 5 in the greenhouse by a modifi ed single seed descent breeding strategy. Successive progeny were advanced under fi eld conditions by a modifi ed pedigree-bulk breeding method under the experimental designations SSD01061 and eventually WA007973. Xerpha was the highest, or among the highest, yielding SWW cultivars in every precipitation zone in the WSU Extension Uniform Cereal Variety Testing Program (EUCVTP) trials in 2006, 2007, and 2008. It was released as a replacement for 'Madsen' and Eltan on the basis of its superior grain yield in Washington's low ( 500 mm AAP) precipitation zones; excellent grain volume weight; strong cold tolerance, and high-temperature, adult-plant (HTAP) resistance to stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici).

Stripe rust (Puccinia striiformis Westend f. sp. tritici) resistance is an essential trait for spring wheat cultivars produced in the Pacifi c 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 the Hessian fl y (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'.

Hard red spring (HRS) wheat (Triticum aestivum L.) grain must have high grain protein concentration (GPC) to maximize market value. The objective of this research was to develop a HRS wheat cultivar with high GPC and durable resistance to stripe rust (Puccinia striiformis Westend f. sp. tritici), a major foliar fungal disease problem of spring wheat. ‘Kelse’ (Reg. No. CV-1035, PI 653842) HRS wheat was developed and released in July 2008 by the Agricultural Research Center of Washington State University. Kelse was tested under the experimental designations of WA007954, H0100092, and HR98036, which were assigned through progressive generations of advancement. Kelse is a semidwarf cultivar adapted to the intermediate-to-high rainfall (>380 mm average annual precipitation), nonirrigated wheat production regions of Washington State. Kelse was released based on its (i) resistance to the Hessian fl y [Mayetiola destructor (Say)], (ii) hightemperature, adult-plant resistance (HTAP) to local races of stripe rust (infection type 0–3), (iii) high GPC, (iv) excellent bread-baking quality, and (v) high grain yield potential in the target production region. Kelse is the fi rst HRS wheat cultivar adapted to the Pacifi c Northwest region of the United States with HTAP resistance to stripe rust. Based on molecular marker analysis, Kelse has the Lr34/Yr18 and Lr37/Yr17/Sr38 gene clusters for rust resistance. Kelse also has exceptionally high GPC compared with HRS cultivars currently in production.
