Overview

Description: SY Touchstone is a hard winter wheat bred and developed by Syngenta Seeds, Inc. SY Touchstone was selected for short plant height, high yield potential, and good hard red winter wheat end-use quality using the modified bulk-pedigree method. SY Touchstone has shown good adaptation in the high to moderate rainfall regions of western Idaho, eastern Washington, north-central and northeastern Oregon and irrigated production in the southern Snake River region of Idaho and the irrigated production areas of Washington. SY Touchstone is moderately resistant to current predominant races of stripe rust with no known insect resistance. SY Touchstone is a short, medium maturity hard red winter wheat that has white chaff at harvest maturity.
