Interpretive Summary: Many soft white winter wheat varieties with high yield potential in the Pacific Northwest lack adequate resistance to stripe rust or are only adapted to specific regions defined by annual rainfall precipitation. The objective of this research was to develop a soft white winter wheat variety with improved resistance to stripe rust and high yield potential across a wider range of climates. ‘Jasper’ soft white winter wheat was developed and released in September 2014 by the Agricultural Research Center of Washington State University. Jasper was tested under the experimental designations 5J061865, 5J061865-11, and WA 8169, which were assigned through progressive generations of advancement. Jasper is a semidwarf variety adapted to intermediate to high rainfall (>300 mm of average annual precipitation), unirrigated wheat production regions of Washington, and also has good yield potential in the lower rainfall areas (<300 mm of average annual precipitation). Jasper has high-temperature, adult-plant resistance to the stripe rust pathogen, is intermediate in height, has midseason maturity, and has an average test weight and high grain yield potential. Jasper has end-use quality properties similar or superior to those of soft white wheat varieties ‘Stephens’, ‘Puma’, and ‘Otto’.

Technical Abstract: Many soft white winter wheat cultivars with high yield potential in the Pacific Northwest lack adequate resistance to stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Erikss.) or are only adapted to specific regions defined by annual rainfall precipitation. The objective of this research was to develop a SWW cultivar with improved resistance to stripe rust and high yield potential across a wider range of climates. ‘Jasper’ (Reg. No. CV-xxxx, PI xxxxxx) soft white winter wheat (Triticum aestivum L.) was developed and released in September 2014 by the Agricultural Research Center of Washington State University. Jasper was tested under the experimental designations 5J061865, 5J061865-11, and WA 8169, which were assigned through progressive generations of advancement. Jasper is a semidwarf cultivar adapted to intermediate to high rainfall (>300 mm of average annual precipitation), unirrigated wheat production regions of Washington, and also has good yield potential in the lower rainfall areas (<300 mm of average annual precipitation). Jasper has high-temperature, adult-plant resistance to the stripe rust pathogen, is intermediate in height, has midseason maturity, and has an average test weight and high grain yield potential. Jasper has end-use quality properties similar or superior to those of ‘Stephens’, ‘Puma’, and ‘Otto’.
