BOUNDARY (HRW): Boundary hard red winter wheat is a high yielding wheat adapted to north Idaho, higher yield environments in southern Idaho rainfed production, and irrigated environments. It is a stiff-strawed cultivar with excellent adult plant resistance to stripe rust, leaf rust, and powdery mildew. Boundary is similar in protein percentage to Garland and Promontory, but lower than Weston (Table 1, 4). Lodging resistance in Boundary has been similar to Stephens but it is taller than Stephens, which would limit its utility under wheel lines. Boundary is moderately resistant to dwarf bunt and should not be produced in the rainfed production areas of the Cache and Pocatello Valleys. Certified of Boundary is available.

BRUNDAGE (SWW): Brundage is a soft white winter wheat adapted to the irrigated production regions of Southern Idaho. Brundage derives from the cross of Stephens/Geneva made by Bob Zemetra’s research program; it was selected in cooperative testing with the Aberdeen research program. Brundage has significantly higher test weight and shorter plant height than other soft white winter wheats adapted to irrigation (Table 1). It has excellent soft wheat quality. Certified seed of Brundage is available.

JEFFERSON (HRS): Jefferson hard red spring wheat has consistently yielded similar or higher than Probrand 751 with approximately ½ a percentage point better protein content than Probrand 751 and a pound heavier test weight in rainfed production (Table 5). It is adapted to higher elevation irrigated and rainfed production in southeastern Idaho (Idaho Falls and higher). It is resistant to stripe rust and moderately resistant to leaf rust and Hessian fly. Registered seed will be available in Spring 2000.

IONA (HRS): Iona is a replacement to the cultivar Amidon. Iona is adapted to lower-yielding rainfed environments as Iona is a relatively tall plant type with high grain protein content (Table 5). Iona is not well-adapted to irrigated production. It is superior to Amidon in milling and baking quality. Foundation seed of Iona is available for planting Spring 2000.

POMERELLE (SWS): Pomerelle was released as a replacement to the cultivar Treasure. It is similar to Treasure. It has better test weight and lodging resistance than Treasure (Table 2). Pomerelle has performed will in the upper Snake River Valley and in the Magic Valley. Pomerelle is a high tillering cultivar with an optimum plant-per-acre number below Penawawa. Milling and baking quality of Pomerelle is comparable to better club wheats. Certified seed of Pomerelle is available.

UTAH 100 (HRW): Utah 100 is a hard red winter wheat adapted to rainfed production. It was tested in Idaho under the breeding line number UT150. It has good yield, test weight, and dwarf bunt resistance. Snow mold tolerance on Utah 100 is similar to Manning. Utah 100 has a later maturity than Promontory and Weston, similar to Bonneville. It is comparable in grain protein to Promontory and significantly lower than Weston or Bonneville. Certified seed of Utah 100 is available (Table 4).

WEATHERFORD (SWW): Weatherford is a high-yielding soft white winter wheat released by Oregon State University. It is similar to Malcolm in yield and has better test weight than Malcolm, but Weatherford may be unacceptably tall in some Southern Idaho irrigated production (Table 1). Weatherford is resistant to foot rot (Pseudocercosporella foot rot). Growers should plant Weatherford if they have found this disease on their farm in the last several years.
