"--- PROJECT TITLE: Western Regional Soft White Winter Wheat Evaluation

PROJECT LEADERS: Bob Stougaard and Todd Keener, NWARC, Kalispell, MTPhil Bruckner/Rhoda Burrows, Plant and Soil Science,Bozeman, MT.

OBJECTIVE: To evaluate soft white winter wheats for adaptability, yield, quality, anddisease resistance.

RESULTS: Yields were drastically reduced in many varieties of the Soft White Winter Wheatnursery due to a combination of winter injury and snow mold. Most severe in the Oregonentries, the winter kill complex in some cases thinned stands by 90%. Apparently however,regrowth combined with spring and summer tillering enabled some varieties to produce a fairyield in spite of considerable stand reduction. Besides the Oregon entries suffering from thewinter kill, there were also large plot losses in the varieties of Nugaines, Moro, Elgin andKharkof. The high yield was 138.9 bu/A (WA 7756) while the mean for the nursery was 92bul A. Eighteen varieties had yields in excess of 100 bul A. Test weights were less than normaldue mainly to environmental conditions throughout the growing season. The mean test weightwas 49.07 lb/bu and the high was 54.55 lb/bu ( OR 851139). TCK smut ( dwarf bunt) wasobserved in the nursery at low levels with only seven varieties having greater than 1% infection.There were twelve varieties that had no TCK infection.

FUTURE PLANS: Continued evaluation of new and introduced lines is planned in the futurethrough cooperative state-wide testing.
