2011 Annual Report
1a.Objectives (from AD-416)
1) Manage gluten strength through cultivar development, cultivar testing and flour quality control measures.
2) Support whole grain initiatives of Kraft Foods through whole grain soft wheat flour research and research in support of white wheat cultivar development.
1b.Approach (from AD-416)
Plan of Work for FY 2012
1)Manage gluten strength
Ohio State University, through separate Kraft funding, will test three Nitrogen treatments and six cultivars for a total of 18 treatment combinations. The N treatments will consist of 20 lbs N in the fall, then 0 units/ac, 1 units/ac or 2 units/ac of N fertilizer per bushel of out yield target in the spring at green-up. We will select two strong gluten (Kenton, Bonafide) and two moderate gluten strength soft wheats (W01-714 and W02-532): all four lack the Bx7oe gene. We will include two strong gluten soft wheat that have the Bx7oe gene and OH04-264-58 which has the Bx7oe gene (Pioneer 25R26 and OH05-264-58). Fungicide will be applied to all plots.
The SWQL will conduct milling and baking analysis on all plots of the trial. Stability of gluten will be measured both by variance of lactic acid and by plant breeding stability analyses.
Genotyping of elite germplasm will be conducted using genetic markers for high-molecular weight glutenins and Fusarium head blight resistance. We will select approximately 1100 genotypes for strong gluten and Fusarium resistance
We will produce milling and baking quality summaries from trials normally evalauted by the SWQL in Ohio and Michigan and compile multi-year summaires of cultivars currently offered for sale in the area of the Toledo flour mill.
The Western Wheat Quality Laboratory will conduct quality evaluations of soft wheat cultivars grown in the area of ADM's flour mill in Cheney WA, which supplies Kraft's Portland bakery.
2) Support whole grain initiatives at Kraft with white wheat research
Ohio State University will test the Uniform Eastern Soft White Wheat Trial and add lines with diverse genomic backgrounds based on genomic selection studies by Mark Sorrells at Cornell University. Yield and disease resistance evaluations of the breeding lines will be recorded and used for recommendations of soft white wheat in the eastern US. Samples of field plots described in Goal 2a will be milled and evaluated for whole grain flour quality using the advanced milling/CoMill bran grinding system. The full description of the milling system was published by the SWQL and Ohio State and used for the nutritional profile studies. Wire-cut cookie analysis will be used to measure suitability for whole-grain soft wheat flour. Non-starch polysaccharide analysis (arabinoxylan and arabinogalactans) will be conducted on the bran.
Managing Nitrogen in Ohio for maximizing profits and wheat quality: trials were established at two locations, Wooster and Northwest Branch near Bowling Green, OH. The previous crop at Wooster was Alfalfa. The experimental area was broadcast with 125 lb/a 20-10-0 prior to planting wheat. (28 kg/ha N) Wheat was planted on Oct. 9, 2010. The soil type at Wooster is a Canfield clay. The previous crop at NWB was soybeans. The soil type is Hoytville Clay. Fertilizer applied was (33.6 kg/ha N) as 300 lb/A 10-26-26. Wheat was planted on Oct. 6, 2010. Subplots within the main plot fertility treatments are six wheat genotypes: (1) W1-967; (2) Kenton; (3) Pioneer 25R26; (4) OH04-264-58; (5) W2-532; (6) SC-1298. The appropriate two main plot treatments at NWB and Wooster locations received 78.4 and 59.4 kg/ha N, respectively, as ammonium sulfate (210 g kg-1) on Mar 31 and Apr 1, respectively, when wheat was at Feekes stage 3. The NWB location received 1.62 cm of precipitation as rain in the 7 day following fertilizer application. The Wooster location received 3.54 cm of precipitation as rain in the 7 day period following fertilizer application.
Cultivar Recommendations from the Long-Term Database: The Soft Wheat Qualtity Laboratory maintains a long-term database of cultivars evaluated in experimental milling. Most of the cultivars in the database are past their peak use for farmers. Of the cultivars in the database that are still in production, ‘Kenton’ and ‘AG 2581’ have the best combination of SRC ratio and lactic acid solvent retention capacity values for cracker manufacture. OH04-264-58 is just beginning production and has similar SRC ratio values to Kenton, AG 2581, and Pioneer 25R26.
Fiber Analysis: Analysis of fiber content is not included as part of this report as no new work has occurred since fall 2010. Discussion of the publication is covered in a separate line of reports and conference calls. The whole wheat milling system will be used to provide samples for the investigation of fiber content as needed and requested. Prior to the beginning of the grant, all currently planned fiber research will be completed.
