1 ^2oo PROJECT TITLE: Statewide Spring Wheat Variety Performance PROJECT LEADER: L. Talbert, Spring Wheat breeder, PROJECT PERSONNEL: D.M. Wichman, CARC, Moccasin J.L.A. Eckhoff, EARC, G.R. Carlson, NARC, Havre R.N. Stougaard, NWARC Kalispell K. Kephart, SARC. Huntley G.D. Kushnak, WTARC, Conrad OBJECTIVE: To evaluate new and existing varieties and experimental lines ofspring wheat under various growing conditions and environments in Montana. RESULTS: The 1998 Advanced Spring Wheat yield trial was grown at two igated and seven rainfed sites across Montana. Irrigated sites were at and. Replicated multiple-row plots were established at all locations using standard research techniques. Heading date, plant height at maturity, yield, test weight, and grain protein contents are summarized in Tables 1,2, 3, 4, and 5. Soil moisture at was excellent at planting, but weather was very until mid-june, when showers occurred in a timely fashion. Dryland yields were above average, but igated yields were very low because ofuneven germination, bird and gopher damage. Havre had very cold, weather early in the season, so germination was slow but uniform. Heavy rain fell in late June and early July, resulting in average yields and normal test weights. Kalispell experienced conditions early in the growing season, but above average precipitation and growing degree days later in the season resulted in ideal conditions for spring wheat production. Moderate to severe tan spot infection was observed. was until mid June, when heavy rains fell. Weather was and warm for the rest ofthe season. Conrad experienced above average precipitation in June and July, but very hot and weather prevailed at the end ofthe season, reducing kernel size and test weights. No disease or sawfly pressure was observed. Moccasin had very weather prior to the growing season, resulting in little stored soil moisture. Precipitation was above normal in June, and severe heat stress in late July resulted in low test weights. Plots at Huntley were destroyed by hail. SUMMARY: Highest yielding lines on a statewide basis were BR2306, MT9675, and MT9712. Highest yielding varieties at individual sites were McNeal at Havre, MT9748 at land, MT9712 at igated, Hi-Line at Moccasin, McNeal at Conrad, MT9675 at Kalispell, Amidon at land, and BR2306 at igated. FUTURE PLANS: New and existing varieties and experimental lines will continue to be evaluated at and the Research Centers in Montana, so that breeders can release improved varieties and producers can have information on varieties best adapted to conditions in their areas.
