Masami showed moderately severe leaf blotching/chlorosis at the Tulelake site. One or more plots of several entries (Stephens, Tubbs 06, Bitterroot, ID9364901A, Masami, Xerpha, BU6W00-523, 99X 1009-19, ORI2042037, Idaho 587, ID99-435, OSUPOP-35-2-CL, Coda, Cara, OR9901619, OR2050293S, and OR2050301S) lodged severely at Tulelake, where grain yields were extremely high.

Several entries (Salute, AP700CL, OR2040726S, OR2040728S and OR2050299S) yielded at least 10,000 lb/acre at Tulelake. Average yields ranged from 3360 lb/acre at the Siskiyou site to 8700 lb/acre at the Tulelake site. ID9364901A was highest yielding at the Siskiyou site, while OR2040728S was highest yielding at the Tulelake site. OR2050299S, OR2040728S, and OR2040726S were highest yielding overall.

Yield Data - Intermountain Fall-sown Winter Wheat

Fall-sown spring wheat and triticale.  The fall-sown spring wheat and triticale test contained 50 entries (24 wheat cultivars, 21 advanced wheat lines, 3 triticale cultivars and 2 advanced triticale lines). Very little rainfall occurred after the end of February throughout California, so the rainfed tests (Glenn and Tulare sites) suffered drought stress. No data are available for the Tulare site: Drought stress was extreme and plants were very short with few tillers; just prior to harvest, sheep grazed the plots to the ground. Triticale entries at the Kings site had very poor stands and low grain yields, possibly because the plots were planted following a summer crop of sorghum-sudan. Uneven irrigation contributed to non-uniformity of yield at the Kings site. Late season moisture stress (early irrigation-cut-off) reduced the yields of later-maturing entries at the Kern site.

Stripe rust was severe on several entries at 4 sites. Entries showing severe stripe rust reactions at one or more sites included Anza, Yecora Rojo, Express, Summit, Blanca Grande, Clear White, Solano, Joaquin, APB W02AZ-365 and WB YU903-283; Entries showing moderately severe stripe rust reactions included Dash 12 and WWW BR5874E. Entries showing low (highly resistant) stripe rust reactions at all sites included Patwin, Lassik, Expresso, Redwing, Blanca Royale, Blanca Fuerte, Lariat, Ultra, WB DA 904-32W, RSI 01W20153, UCD 07013/24, UCD 07013/30, UCD 0715/9, UCD 07103/57, and Trical Brand 105 triticale.

Extremely windy conditions just prior to harvest caused grain shatter at 5 sites. Entries showing moderately severe to severe grain shatter at one or more sites included Mika, Dash 12, Expresso, UCD 06010/5, APB W02AZ-365, RSI 00WB80722, UCD 07013/24, WB BZ904-331WP, WWW CNBR9330, APB W05AZ-137, APB W05AZ-149, and APB W05AZ-176.

Grain protein content of samples from three sites in the Sacramento Valley and three sites in the San Joaquin Valley was measured. Average grain protein content ranged from 11.20% to 15.02% for samples from the Sacramento Valley and from 10.29% to 13.58% for samples from the San Joaquin Valley. APB W05AZ-137 had the highest grain protein content overall. Quality evaluations (conducted by the California Wheat Commission laboratory) of samples from the Kings site showed that Blanca Grande, Mika, Solano, Patwin, Otis, Expresso, Redwing, and APB W05AZ-137 produced high loaf volume and satisfactory overall bread score.

Average grain yields ranged from 2370 lb/acre at the Glenn Rainfed site to 6720 lb/acre at the Kern site. RSI 01T40207 triticale was the highest yielding in the Sacramento Valley (Blanca Fuerte and Ultra were the highest yielding wheat entries); RSI 01W20153, in the San Joaquin Valley; RSI 01T40207 and WB ACS 55304 triticale entries, in the Imperial Valley (Ultra, Lassik, Blanca Fuerte, and Summit were the highest yielding wheat entries); and Joaquin, at rainfed sites. In the three-year period 2006-08, Trical Brand 118 triticale was the highest yielding in the Sacramento Valley (Blanca Fuerte was the highest yielding wheat); Redwing, Blanca Grande, Joaquin, and Blanca Fuerte, in the San Joaquin Valley; Summit, in the Imperial Valley; and Cal Rojo, at rainfed sites.
 
Yield Data - Fall-sown Spring Wheat and Triticale

Spring-sown spring wheat. The spring-sown spring wheat test that was evaluated, the Oregon Spring Wheat Elite Yield Trial, was provided by Mike Flowers, Extension Specialist, Oregon State University. The test contained 30 entries (14 cultivars and 16 advanced lines), and was evaluated at three sites. Saturated soil conditions through early summer resulted in severe root rot and very low grain yields in portions of the test at the Lassen site. Affected plots were non-uniformly distributed, so yield variability was very high. Two or more plots of the following entries were in the most severely affected portion of the nursery: Cabernet, OR4031111, Clear White, and Blanca Grande. There were scattered foci of BYD, root rot (probably Fusarium), and bacterial streak (Xanthomonas translucens) at the Siskiyou site. There was no entry-specificity regarding disease incidence/severity.

High yield variability at the Siskiyou site is partially due to non-uniform sprinkler irrigation; a portion of plots in the 1st rep received poor coverage, resulting in low yields (the following entries yield about half as much in the 1st rep as they did in the other two reps: BZ901-717, OR4031111, Patwin, RSI10348W, 37C-3, UI Caltaldo, Nick, and Alpowa). Several entries (ID 0377S, BZ903-445-WP, OR4041451, Nick, Louise, WA008039, and Alpowa) at the Tulelake site had severe lodging at harvest. Average grain yields ranged from 2100 lb/acre at the Lassen site to 7860 lb/acre at the Tulelake site. BZ604-002 was the highest yielding at the Lassen and Siskiyou sites; and UI Cataldo, at the Tulelake site. BZ604-002 and Hank were highest yielding overall.
 
Yield Data - Intermountain Spring-sown Spring Wheat

Durum wheat. The durum wheat test contained 35 entries (15 cultivars and 20 advanced lines). A few plots at the Kings site had poor stands and low grain yields, possibly because the site was planted following a summer crop of sorghum-sudan. Uneven irrigation contributed to non-uniformity of yield at the Kings site. Late season moisture stress (early irrigation-cut-off) reduced the yields of later-maturing entries at the Kern site.

Stripe rust was moderately severe to severe on several entries (UCD 06222/53, RSI 06WV141, RSI 06WV164, UCD 06222/52, and WWW CHD1126B) at the UC Davis site. Lodging was moderately severe to severe for several entries (Kronos, Westmore, Maestrale, WB YU 803-52, UCD 06222/53, APB D257-11/2, and APB D257-11/3) at the UC Davis and/or Imperial sites.
